DX11 Performance

[_Milky]

Just thought I'd give a quick post on my experiences so far. This update is definitely a big step forward for this game and does look amazing. Unfortunately, I'm running AMD and by the looks of it most AMD users are having a hard time running DX11 at the moment. I've lowered and messed with the in game settings a bunch and the highest fps i got on low settings was 39.

I also get a little stutter here and there, but it's mostly just fps problems. Post proccess I tried on medium, low, and off. None made a difference to the FPS. AA was also turned off and got about a 4 FPS boost, not much.

I'm running:
- AMD A10 6800k
- Sapphire R7 370 4GB Nitro
- G-Skill 16GB RAM (Can't remember the speed)

I can run DX9 version at a stable 90 FPS on high settings. I did see a huge FPS hit coming with this update since it is a Beta and isnt fully optimized yet. Just thought I would put this out there in case any one else is having framerate issues.

If anyone has any tips to get an FPS boost in DX11, please do let me know. Not sure on what I can do to get a smoother experience at the moment. In the meantime I'll just run DX9 and keep up to date with the coming updates.

Cheers.

Well I'll throw this in here for what it is worth, firstly my system spec is as below:

AMD FX-8350 @ 4.5Ghz
MSI R9 290 Gaming 4G 1040/1400 (Crimson Driver Version 17.5.1)
Corsair 16Gb @ 1866Mhz
Single Screen @ 1080p

I downloaded the DX11 Beta version when it was launched on 1st May and no matter what I did I had awful performance. The test I did was running some content which had been updated for DX11 which was Silverstone and the Nissan GT500.

With AA on 4/5 and PP on high/ultra with a 20 car grid (all vehicles visible) with game settings as high as I could set them and sunny clear weather condition I was seeing an average of around 15-25 FPS depending upon where I was on the circuit and how many cars were around me.

To try and improve this I did all what Studio 397 suggested and still nothing seemed to improve things, so I tried with settings as low as I could get them both AA and PP and also the in-game settings, the game seemed to perform a little better, around the 25-50 FPS mark but it still wasn't very playable, I even went as far as deleting the game and all of the remaining files including my player profile and still this did nothing to improve the game, so I went back to DX9.

I gave it a few days and installed the DX11 Beta version again after the 2.1Gb update to the stable branch of the game and peformance was much improved, it has improved so much now to the point that with AA on 4 and PP on high with all game settings maxed out apart from shadows because of some black box bug on the ground, they are set to High instead of Maximum, I am now getting with the Nissan GT500 on Silverstone with a 30 car grid with 30 visible vehicles and the same sunny weather conditions no lower then 40 FPS sat on the grid waiting for the race start, once the race was running I was sitting between 50-80FPS the whole time (even in the main pack of cars) which is a MASSIVE improvement over the course of a few days.

Your performance does seem a little low, I should think you'd be getting a higher frame rate especially with everything set to low, if you haven't update your video card drivers and also ensure you've done all of the suggested performance Studi 397 have suggested such as deleting all the files from the CBash and Shader folders in your Userdate/Logs folder in the rFactor2 install directory, other than that if that doesn't work, hang in there as I'm sure performance will continue to increase over the coming days/weeks.

what resolution you running at?

with dx11,
even before the latest little patch i was getting over 300fps on minimum settings on an R9 290 (at 1080p)

You likely have not enabled the post processing effects in the launchers video options. I too was surprised at the performance I was getting having read so many people having issues then I realised I had not enabled PP. Once I had done that, in certain situations the performance takes an absolute nose dive.

[Binq]

The OP has tried with PP off, still low performance for him.
Granted, the GPU he has, R7 370, is considerably slower than the one i tested with, but it shouldn't be more than 5x slower.
He writes:
"Post proccess I tried on medium, low, and off. None made a difference to the FPS. "
" the highest fps i got on low settings was 39."

Sir Ropey has helpfully re-iterated Studio 397's suggestions:

"Your performance does seem a little low, I should think you'd be getting a higher frame rate especially with everything set to low, if you haven't update your video card drivers and also ensure you've done all of the suggested performance Studi 397 have suggested such as deleting all the files from the CBash and Shader folders in your Userdate/Logs folder in the rFactor2 install directory"

These are good things to try, as the framerate the OP has looks a little low.

Other things i can point out is that making sure that you select only clear weather (no clouds) seems to make a considerable difference in performance. The clouds seem to tank the FPS.
Also, backing up and then deleting your player json file can help.
Some people have said that they resolved performance issues with a complete re-install, including unsubscribing from all non-DX11 optimised content.

I forgot to mention this was a completely fresh install. Just updated to windows 10 a couple days ago. During this testing I was also running at 1920x1080.

I'll definitely mess about with the settings some more and see what i can get out of it.

I'll update further once I've done some testing.

I just looked st Studio 397's recent post on their website. It looks like i have been using the 'older' version of the dx11 Beta... I chose "you can optionally switch to the “v1108-dx11-open-beta-last-stable” build, which will point to an older build."

I will now try the right one and get back as soon as possible. Thank You for the help everybody.

FWIW
FX 8330 @ 4.2
16G ram
MSI R7 360 2G
I too did not have much more than minimal graphic performance on the May 1 upload.
Second download and I changed a few things following instruction here under guides I think.

It has become satisfactory to me now. A few changes by myself and improvement of the beta I like. I am using the updating beta because of this.
Wishing for a 1967 Le Mans for rF2.

I to had performance problems with the DX11 update. I am running a ASUS g11 GeForce GTX 980 intell i7 6700 16gb ram ASUS montior 144 hz. Without DX11 run game with all on full at 130fps with DX11 25 to 35fps turned thing down to low med not much better 40fps and runs choppy. DX11 sure will look and be grat if it will run on a good fps.

R9 290 over 300 fps DX11 with everything on low, make sure you follow the dev's instructions for the DX11 beta for optimal performance. Heres some of them and some other tips from other users:

-Disable all third party plugins for DX11 and VR:
Open the file CustomPluginVariables.JSON located in rFactor2/UserData/Player
Backup the file, then Add a '0' to all third-party plugin entries, example: " Enabled":0

-Remove TrackMap Plugin 'd3d9.DLL' from ...rFactor2/Bin64

-Clear the contents of your Shaders and Cbash folders. The Two folders are located in rFactor2/UserData/Player/Logs. Only remove the contents of these folders, leave the empty folders.

-Verify your game cache

-Subscribe only to DX11 updated content in the workshop:
http://steamcommunity.com/id/studio-397/myworkshopfiles/

-Make sure to select only "clear" weather before starting the race, clouds kill performance

-Backup and then delete your player json file

That's great but a lot of people are wanting to have a nice looking game too. As I implied earlier, turn on post processing in the launcher for a start, bump your settings up to high and use level 4 AA. Report back on your performance then.

After the latest update just now, its running superbly, even in VR - AA enabled, high for track and textures, shadows on, etc, im stoked! Great job devs!

[Yoko]

just downloading the big update... the small fix before made my game look good again visually and performance wise... thanks so far
