How to setup Assetto Corsa with HP Reverb G2 to get 90fps and crystal clear picture - JUST 2 LAPS VR

[@C13Automotive]

This is looking really nice. Shame my eyes can't handle long in an HMD. I have to admit I was not considering VR performance while developing the filter, I'm very glad performance is good and super happy you enjoy how it looks. I do have a suggestion for settings though; with Sol 2 the performance cost of having reflections set at more than 2 faces per frame can be pretty high (though i'm not sure if that goes for 2d as well as 3d clouds). So for even more performance, you could turn those down. CSP can reproject reflection faces, so the visual gain of having more than 2 faces per frame is minimal. Thanks again for the shoutout and nice words about the filter.

[@just2laps-finestsimracingv70]

Hi, thanks so much for your comment ! I feel very honored to get a reaction from you, the developer of the filter 👍 I have to say that this is indeed the best filter I have ever used in AC regarding optics and performance. I was trying a lot of filters and really not any could satisfy my needs until I discovered yours. Thanks a lot for the hint with the reflections, I'll try that out for sure. At the moment I have no problems getting 90 fps when driving without simultaneously recording and reducing the mirror screen to minimum resolution. When recording I am losing about 10 to 25fps depending on track and amount of cars, so I am happy for any single fps I can gain without losing too much picture quality. Have a nice day and keep on with your fantastic work ! 👍👍👍

[@simssim7821]

Finally, I am getting close to 90 fps. 89.3. : ) Thank you for sharing and your efforts. Really nice! I install your recommended pp filter and experimented with PURE. Both works fine.

change your max frames to something like 92 instead of 90... That will allow the headset a liitle more room to hold that constant 90

[@christianhofmann7182]

Thank you for your informative video. Perfect German English, I would sound exactly like you 😀. Are you sure that the resolution in CM-settings-Assetto Corsa- Video has impact to the VR performance? It is overwritten by the VR video settings as far as I know. I have problems with very big user interface of the CM apps in AC in game when I lower the resolution under my 4K of the screen. 👋

[@just2laps-finestsimracingv70]

Hi and thanks four your comment mate ! The setting of the resultion affects the size of the mirror display on screen as well as the appearance of the "starting screen" and the icons in game e.g. seating position. It really makes a difference if you are going to use a mirror screen with 640x480 or 4k resolution. The rendering work for the GPU is the same as this is depending on the VR settings but it needs some video memory and performance too for doing the display of the mirror. Impact is not too big but from my expecience it is a difference of about 5 to 8 fps between lowest setting and 4k. And sometimes every single fps makes a difference between smooth movement and stuttering. But I agree that the big icons in the UI are not so comfortable to handle, but I get used to it by time. Have a great day and keep on racin' !👍

[@SMONclips]

Works perfectly. Went from 45fps to 90

[@albundy1281]

Thank you so much for this, i bought the headset last week and these settings instantly worked almost perfectly on my RTX 3080ti. Saved me so much time and nerves! One thing i am curious about is the vsync option, what advantage is there by turning it on? From my understanding vsync creates more input lag, which is especially bad for racing games.

[@ronaldnoble8297]

I think the filter didn't make much difference to the FPS, I prefer _SoL as the cockpit doesn't look so bright. AMD FIdelity has to be on Quality and High sharpening to get 90fps. I find it makes everything a bit blurry at a distance.

[@just2laps-finestsimracingv70]

Hi, thx for your message. I have checked several filters and finally used the C13 camera obscure. But I think the usage of the filter is more a decision of personal taste and depending of the screen capabilities too, the C13 was giving me an advantage of about 5fps compared to others though.

Thanks a lot for your video. After configure the settings Assetto Corsa is fantastic. Before and I don't know why I could not see it as good as now. Only one thing. Before using your settings when I run assetto corsa, the window in my monitor was black but now, I can see also the game both in the VR headset of course and also on the monitor...and in this way I think it reduce the performace.. Do you know how to set again the screen to black in the monitor? I have revieved your video and the configuration and I can not see where I could change it... One more thing What's your GPU ?I have a NVIDIA RTX 3070. Thanks a lot once more!!!

[@just2laps-finestsimracingv70]

Thanks for your comment mate ! When not recording I usually reduce the window size to 640x480 at 24Hz in the Assetto Corsa Display settings, full screen disabled, this gives you the best performance. In the WMR window you can stop the preview for saving performance by clicking on the "II " button in the middle of the lower part of that window. Hope that helps !

Hello again. I didn't know that you could pause the video in the WMR :-). You always learn something new every day jejejeje. I have tried lowering the quality to 640x480 but the problem is that all the objects in the HUD change also their resolution so you see them very big now on the VR... :-( Some solution for that ?

@@1971JESSA Hi, no. There is no solution so far. Handling is a little bit strange, but I learned to get used to it. You can also try some other resolutions like 800x600 or 1024x768 which does also not impact performance too much but gives you a better handling in VR.

[@alvarocortes9448]

I don’t know if you may help me. I’ve got a 3090 with an I9, with your specs Or lower (for example lowering resolution to an 80%) I can’t achieve 90 fps, and in a circuit online like hi highlands, in some places I can’t show 75 fps. I can’t understand what I’m doing wrong. Do you have game mode on? I dont know how to find where is my problem :(

[@just2laps-finestsimracingv70]

Hi, from the system specs it should run without any problems, so I assume that something is wrong in your config. Maybe some hints that can help. I graphics settings please ensure that "hardware-accelerated GPU scheduling" is set to off. Sound a little bit paradox but this is contra productive for 30xx cards and will help only older cards. Game mode I have set to off. In the WMR please ensure that dispplay mirroring is switched off. Please check the properties of the "acs.exe" file from AC and check "Disable Full Screen optimization" as well as "High DPI scaling override" by application. For detailed settings in AC CM and CSP I'll put you the links of my config here (I am using now the 0.1.79-preview5 version of CSP as well as the latest config of CM) : CM settings : acstuff.ru/s/ThUAd7 CSP settings : acstuff.ru/s/RC8WyK additionally I am using the C13cameraobscura PP filter with the latest version of Pure. CM, CSP and Pure are the paid full versions from Patreon . My I9 I have overclocked a little bit to 4,5MHz all cores and the cache to 2.8GHz. My GPU is a little bit overclocked too with the AORUS Engine tool set to "curve". Hope this helps. NVIDIA Experience is NOT installed becuse it caused me problems all the time. If all that things do not help anyway it might be an option to completely remove the NVIDIA driver with the DDU tool and re-install the latest version. I had similar problems in the past and that helped a lot. If you have any more questions please let me know.

[@meeks726]

Would you recommend Real Head Motion/NeckFx when using VR? Or does Lock To Horizon just work wonders?

yo guys, what do u think, should i buy g2 for my setup, what is 3060Ti, 32gb ram, and i7-9700? id like to play with assetto corsa. Will my card run it well? or should i buy another vr?

[@just2laps-finestsimracingv70]

Hi, I think it should work with your 3060ti. Assetto Corsa is, if configured well the most performant game to play in VR. Ok, I have RTX 3080 but it should also run with you 3060ti, maybe not with full options enabled but it looks pretty good even with some of the performance eating options reduced.

[@PaulChoix55]

I use a RTX 3060 coupled with a Ryzen 5600x to run my reverb G2. With proper settings I can even get Shutoko revival to run mostly above 80fps. Otherwise, Motion vector does a surprisingly good job at smoothing things out without looking odd, as it cuts in half the rendered frame and fills in the gaps to give you 90hz. The main thing is to reduce rendering resolution to something closer to 2400 x 2400 instead of 3000 x 3000 (100% scaling in steam VR) which will greatly help framerate.

[@jackr.749]

Great Video, that filter you are using, does it require SOL to work or it will work fine with just CSP without SOL or PURE. I don't use SOL, too much of a performance hit in VR and I have AC looking pretty good without it. And yes, FSR does help with the frame rate and appearance. :)

[@just2laps-finestsimracingv70]

Hi, it needs CSP and SOL too, but it has no impact on performance. Without recording a video simulaneously , I can run AC in VR mode with everything set to max in graphics options including all addons like Grass FX etc. Only have lowered a few parameters like mirror screen resolution (minimum), smoke generation, shadows etc. and I am getting stable 90fps

[@derekkozacko1382]

In case you or the other poster (with the 3090) still has this issue (or someone else comes across this), some AC Apps seem to tank performance in VR. I was frustrated as I was initially able to get 90 fps easily (with the settings in this video) and then, sometimes, I was stuck in the 60-75 FPS range and it was very "stuttery." In my case, it turned out that the app, Traces, was responsible. Whenever I have that enabled, VR FPS and performance are really bad. When disabled, I am able to get 90fps constantly. Oddly, I don't notice any issues with Traces and my triple screen setup which ends up being 10320 X 1440 (34" 21:9 center with (2) 27" Sides in portrait mode. This shouldn't be much different from VR.
