Oculus Clarity
The clarity of VR in AC is horrible. When I use my Oculus with Project Cars or RaceRoom I get great clarity up close and far in the distance, but for AC everything looks pixelated the further you get away from your vehicle. I understand this is an issue across all games through VR but AC is ten times worse than any of the other Sims I play. I have modified the AA values in the Oculus SDK to 1.5, I've also modify Steam to have AC start in VR and changed it's value to 1.5 as well but this only brought minimum Improvement and if I go any higher than a 1.5 value I get artifacting and shuttering in the game. My setup includes an i7 6700k overclocked to 4.5 gigs, I am running a EVGA FTW 1080 overclock to 2058, both the cup/gpu are water cooled and never run higher than 48 degree F, and there is 16g of ram at 3000 speeds. With these specs and the fact that I am getting perfect visuals in the other two SIM's I don't think Hardware is going to be the cause, there must be something on the software side, is there anyone else having this issue? Has anyone solved this?

You shouldn't be starting the game in steam vr. Start it normally.(it's not optimized)
Also- I have a very similar setup and I had a similar issue when using oculus.ini to increase pixels. I solved it by using Nvidia DSR in Control Panel. (Manage 3d settings) Set it to 2.0 and select the resulting resolution in (Change resolution) . Then select that resolution in the games video page. Pick Oculus in video setup. The only issue I have using this method is that it changes your resolution globally for other apps so I had to adjust font size in the desktop video settings.

You just need to go into AC main folder and go to the cfg folder and look for oculus.ini and change the `Per Pixel Display` from 1.00 upwards= start at 1.25 (25% resolution bump) its basically super-sampling- you don't need to touch Nvidia DSR or anything else.

Turn off AA in AC, its not worth the performance hit and just up the Per Pixel Display (super-sampling) until you're happy.

My point is that [oculus.ini ppd] hits performance when pushed past 1.25 and at 1.25 you only see minimal improvement- where as nvidia DSR will do 2.0 @90fps. (on my rig)


BTW wesilsp- If you want to play with the graphics you can try some mods like Wagnum's from race department. I've found that they balance the textures and lighting and generially look better in the rift.
Mr Crisp Feb 12, 2017 @ 2:08pm 
If you can hit 90fps with Nivida DSR at 2.0x, presuming it is actually super-sampling to 2x, then there is no reason why you cannot maintain this with any other type of super-sampling.

2715x1527 is nowhere near 2x the native panels total resolution of 2160x1200- or do you mean a custom resolution and then 2x DSR on top of that?

Per Pixel Display is a better way to super-sample for VR imo, especially if you are using a Rift native because any framedrops resulting in a too high PPD will mean ASW kicks in and you won't even notice the performance hit and using Oculus Runtime do super-sampling is probably better anyway.

Theres an OCULUS tool you should download to use with PIXEL DENSITY. It is inside the OculusSDK download > tools > oculusdebugtool. Use this for every Oculus game, not just AC.

Also I have no problem with AC being a little "worse" on the eye candy compared to pCars. The difference in FFB between the 2 is hugely in favor of AC, I don't need to go into a rant as to why AC>pCars. There are plenty of other reasons, but most importantly the FFB should be the entire reason anyone plays any RACING SIM.

It is if you have not set up ffb on pcars. If u have its comparable in that some cars are better in each sim over the other.

There are also plenty of reasons to chose pcars over ac. Both are good at some things and worse at others.

I had plenty of hours on pCars, no where near as many as you. But I don't need 1k hours to tell you the truth here. Even a simple google search will bring you back complaints about everything I state here.. I was even setup in weekly leagues. The FFB is no where near on the level of AC and they are no where near iRacings FFB levels. FFB on both these games destroys pCars and that is exactly why pCars 2 is having a revamp of their FFB system, tyre models etc. In stead of fixing or working on whatever they have in pCars1, they want $$ millions more to fix the issues the first game had... Amazing how people still support these guys.

Horrible FFB, a dead community (compared to both AC and iRacing) a lead developer who complains about people reporting bugs, abusing people on forums in a public space, straight up lying about certain features, horrid A.I.... need i go on?

Maybe they'll address all the issues everyone had like aggresive snap oversteer in every single car in the next game, right?

I mean I can see why you are here saying it's a good game. It's the only "SIM" racer you've been playing. I don't mean to knock the game you love so much. If people thought like you, there wouldn't be 0 people on every single server I see listed whenever I decide to hop on it lol. But whatever man, every game has their fanbois.

I have been playing sims for over 20 years. Including Geof Crammond GP series, rfactor, GTR, GTR2, GT Legends, Race series, Raceroom, iRacing, rFactor 2, AMS, Assetto Corsa etc... (not listing the console racers for obvious reasons)....

Could not disagree more with you on FFB in pCars - However I can understand you coming to that conclusion.

It can be dialed in to be very very nice... however without instructions you have no hope in hell of getting there and that is where the failure is and also what they are improving (as well as the tyre model etc..).

It was far to complicated and you simply wont get there unless you were one of the very small % of people who actually understood all the sliders.

On top of that the default is absolutely horrendous because Steering Gain was set to 200 and that makes the FFB terrible. Dilaing that back to 100 and its already massively improved. Then add Jack Spades files and set up the FFB for your wheel from below and you have a great feel in pCars (some cars I agree are meh - but there is a great selection that just feels right to me).

http://forum.projectcarsgame.com/showthread.php?35147-Baseline-Wheel-FFB-Values-Google-Sheet-amp-FCM-Universal

Some cars are fantastic in pcars others are not. What frustrates me the most is just how different grip I feel from some tracks. ie Silverstone, Brno, Road America I just dont feel the car connected - however load up Oulton Park, Donnington, Watkins Glen, Brands Hatch, Snetterton, Le Mans, Norschleife, Cadwell Park or so and I dont think AC can touch the experience most definitely not in terms of offline racing.

What does surprise me is that you feel iRacing FFB is anything to shout about that to me feels terrible - there is simply no FFB clues given your going to slide at all.

Ultimately I prefer some things from both Sims - the new Porsche LMPs and Cup Cars are frankly ridiculously good fun and I dont think most pCars LMP cars touch those.

Ill continue to use both - but I started with AC and when pCars came out I clearly had a preference.

I've tried every possible guide, I read through the spade guide for weeks trying to come to my own conclusion. I tried his own file changes and it was some what better but it still left areas lacking. The reason the aggresive snap oversteer happens is because of the way FFB in the game works. They are reworking the FFB so snap oversteer no longer happens. This apparently isn't something they could of done in pCars 1 becuase of the work required. So, if its not broke, why fix it?

I'm not saying you don't play/use racing sims, i ment its your current most used sim not really touching anything else. With no racing sim comign even close to the hours you have on it. I dont mean to offend you with it. Most of the other racing sims you've played are actually better than pCars ffb imo lol. I'd say its personal pref but it couldn't be. AC and iRacing put pCars community to shame.. I literally never see a single person online.. heaps of servers just no one online racing.. The last 2 leagues I was in both called it quits and moved to AC. And like I said before, the A.I is horrid.

I know exactly when I'm sliding in iRacing. I know exactly when my brakes lock up. These 2 sensations are entirely missing in pCars. If you actually get it out of pCars I salute you, cause not even spades files made me feel any of it. You should actually write a detailed guide how to fix it. It might make a lot of racers come back

Too much text to use as a reply but @Chicken Pants...

"if its not broke why fix it"

If thats the case we would never have needed another game after GP Legends or GTR2 or any other top notch game in any genre.

It sold over 2 million copies and there are plenty of people happy with it.

Its not perfect - far from and thats why improvements are needed not just on FFB but a host of other areas too.

In addition we get a bucket load of industry leading functionality coming up too hopefully in Pcars 2.

My guide would be read Jack Spades post and the per wheel settings as linked above and your good to go (although Im happy to post my T300 settings in game if it helps some find it a bit too strong - but there is no clipping for me).

I get more control than over AC and most definitely miles more over iracing.

The good news is though we dont need to agree - Im happy there are so many sims/racing games out there now - it means we can all be very selective. I totally get people thinking pcars FFB is broken if they have not set it up but once it is I get plenty of signals telling me what the car is doing and going to do.

As you say you prefer AC/iRacing and I dont - I see merit in all of them though and give them their dues.

A lot of people rave over rfactor 2 and AMS and laugh at anyone calling AC a sim - I dont agree with those guys either - bottom line we are all just playing games no matter how hard we convince ourselves :)


Oh well !

After lots of testing by folks on the official ac forum it's agreed that nvidia DSR has no effect on the image being rendered in the rift

'Yeah, DSR and resolution settings only affect the HUD. The config edit is the only way to improve the Rift render res'

Well where do I start.. You keep avoiding the biggest issue pCars has ever had.. Snap oversteer in every single car caused by the games FFB and physics.. You are yet to even aknowledge anything regarding it.. Just because it sold a lot doesnt mean anything. Do you really think there are 2 million + people wanting to become a better race car driver? Lol. It was sold on consoles. Forza is sold on consoles too. If you wanna think like that, FORZA must be the best racer ever made considering its probably sold the most. But again, that game has horrid FFB as well which is why they are fixing it in their next game. But sorry, pCars is not Forza they can't just release a new "sim" every 1-2 years.

Also, a lot of those console version were returned once they found out its nothing like Forza and its a pain in the ass to get it running on a controller. Well where I work they were returned in huge amounts of numbers. Maybe I need to start sourcing this stuff so you actually have proof and see wtf I am talking about.. or you could google all these issues.. its not like there isnt a 92012901209 threads regarding all these issues.

Did you not read what I said? I literally read through the spade files for weeks and tried my own after his files were barely any better than stock.

The simple fact is, the game is dead. There is no multiplayer (another fact you are avoiding).

They cant fix snap oversteer without releasing A NEW GAME. (another fact you are avoiding)

They scammed Oculus users.

They abuse people on forums.

They abuse people reporting bugs.

They can't fix A.I without A NEW GAME.

If you really want to support developers who act in such a manner I feel sorry for you. I really do. Not just because you think pCars is the bees knees, but that you will happily be abused for trying to support a company and better the "sim"

I've never seen a single person rave over rF or AMS vs AC. Where are these rF/AMC people? I've never ever seen one person come in here, bad mouth AC and try get them to come over to rF/AMC. I have however on a weekly basis seen people calling out pCars and how horrible it is compared to AC.

You have more controll in pCars than AC? I call straight up BS on that. Show me you drifting the RADBUL around an entire track please. You can't even catch slides in pCars and youre telling me you have more control? lol.

You don't use DSR. You use the OculusDebugTool to change pixel density. It is doing what DSR would be doing but on your Oculus. Even if you set it to 2.0 a 6700k+1080 probably won't even be able to handle 90fps. Start at 1.2 and work your way up.

Why do you need to do it in the CFG when you can just the debug tool which applies to all OCULUS games while it is open??
