I redid my Oculus CV1 sensor calibration and it seemed to help a bit with any stutter, maybe my sensors were out from the start, could be placebo, but Im only getting a stutter at the start line and it goes away once I get moving 1700x & 1070 medium gfx, logitech g920

Why is everyone so self important and resort to yelling? Maybe it's because I'm older. But asking for help instead, which is readily available, tends to yield better results.

I highly recommend everyone force running the game in windowed mode and at a 720p.

It seriously smoothed the game out and it runs perfectly now. I had the stutter/delay. And now it's resolved.

This is Disgusting on how to treat people reading through the forums some people say that the Oculus version is far better than the Steam version they can play ultra setting in VR, Is the oculus store Version better optimised than Steam Version? I bought the deluxe edition on the day VR was Released as I will not play Flat screen anymore I was hoping it would play as good as dirt rally 1 but it plays awful in VR I have a I9 Running at 5.3GHZ and a RTX 2080 TI 32 GIG Ram. using a Oculus rift S Which I bought just For Dirt Rally 2.0. And I cannot play this above Medium OMG WTF Plays fine on Ultra on Flat screen But VR is Horrible Juddering and incosistant frame rates, You need to do something about this as I refuse to Buy the game again. Not Impressed.

I'm running the Steam version, I dont have stutter, I dont have input lag, I play on most settings at Ultra and just drop off things that make VR worse.... like motion blur, Ambient occlusion etc. and mines running extremely well indeed. I can say it's very likely that the Oculus store edition is probably not forcing any SuperSampling by default and I think this is the only real difference between the versions for performance. BTW I also set SteamVR to direct mode so doesnt autoload steams VR living room junk.

So I'll put it down to how it's setup, many people dont even check to see what Super Sampling is defaulting to automatically on Steam, mine is typically 150% so all I did was knock down to 1:1 (100%) SS, problem gone, and even have some headroom to push back up to maybe 120% as the GPU was hovering around 70% load. (gtx1080ti).

There's still some fixes needed to the VR game, such as the incorrect HUD being squashed on HMD viewpoint which also tracks to direction car faces not the HMD direction, and the fact it refuses to play the non-VR edition even when fully removed my CV1 from the sockets, but the devs are addressing this in the next update.

Meanwhile Hello games have had two hotfixes for No Mans Sky VR in 48 hours... so yea.... bit shabby on the time a big dev team need in comparison to make a simple VR on/off tick launcher. I'm not saying Hello are doing anything better, they ported to the Vulkan API from OpenGL and many players are moaning they dont have modern GPUs that support Vulkan, so they are also alienating some players, so it's swings an roundabouts.

Ultimately I never bought DR2.0 for VR, much like I didnt for DR1, I bought it cos I love Codemaster's driving games, and really appreciate they bothered to add VR to them for free (looking at you Bethesda you dodgy f***s), so can we have F1 VR next eh? or a new TOCA game please :)

Hey Guys! Just bought Dirt Rally 2.0 to play in VR (with my Vive) but Steam doesn't think it's a VR game. Any ideas?

What exactly is it doing? Any error messages?

Nope,no error . It just wants to launch the game in Theater mode like other non VR game. I already UNselect the option "launch game in theater mode in VR" in the settings.

And the game is not in the tab VR game like the others.

Hey jazzy,
This is an issue we're working on, but if you have SteamVR already open when booting the game, it'll give you that warning. But pressing ok should launch it anyway, if you have anymore issues, make sure the "Desktop Home Theatre" mode is disabled too (or just have steamvr closed down before booting the game with a VR device in)

Hey Kristen! I've tried to launch the game with and without Steam VR. In both case, the game launch the VR Theater mode athough I've unselected this option in the settings.

I know this sounds like a un optimal solution, but you may have to reinstall DR2. Unless there is a something going on with your config INI file.

Poor Oculus performance without Oculus Runtime support and consistent frame drop/stutter. Not confident it'll get fixed and support the oculus runtime.

I'm not disabling USB devices and wasting my time doing workarounds and fault finding.

Refunded through Steam support. Will wait to see Codemaster's ability to fix their product.

Where you put the windowed mode and put in 720p?

Edit C:\Users\PC NAME HERE\Documents\my games\DiRT Rally 2.0\hardwaresettings\hardwaresettings.xml with a text editor like notepad++

look for where is shows resolution in the graphics card section and adjust accordingly, and save.

[binz3n]

Thanks!!

I'm using the default 1080p desktop output myself, would like a way to have dual eye output but the stereo option doesnt seem to be the one for that, as by default it's outputting one eye stretched instead. see video just made https://youtu.be/psp6I5eMYKw

Correct. Why this resolved the problem, for me, I couldn't tell you, but it has. So I hope you have luck as well.

So this game seemed to run very poorly on my setup: 2080 Ti, 9900KF @ 4.7GHz, 32GB DDR4 3600, Valve Index @120Hz, and I tried all the various fixes described in the guide linked in this post, but it still seemed like something was wrong with the head tracking. I even tried the change to the 'C:\Users\PC NAME HERE\Documents\my games\DiRT Rally 2.0\hardwaresettings\hardware_settings_config.xml' file to set the resolution to 1280x720 and Windowed mode which had no positive effect to the game for me. But in that config file I noticed the FPS was set to 100 Hz, so I changed that to 120 and now this game is running very nicely on my setup!

There is still a small mount of head tracking lag that is noticeable at the start of a race if I move my head quickly, but the race itself feels perfect. I also have motion blur turned off and I turned the simulated cockpit vibration totally off in the VR Comfort settings, but otherwise all the graphic detail settings are cranked to the max. I played a lot of DiRT Rally in VR with the original Rift and this is blowing that experience out of the water. The larger FOV, higher resolution, and increased framerate of the Index with the upgraded graphics of this game are a sight to behold.

It seems to me like the bit of tracking lag I am seeing is more tied to the game view adjusting to the HMD position rather than a performance issue due to graphics settings. When in motion this game runs completely smooth for me with maxed settings and the small head movements glancing into mirrors and corners feel smooth.

So Valve Index users, be sure to set that FPS field in the above config file to match whatever you have the headset set to and you should see way less judder.
