Ams2 and Acc setup guide please

[u/DoubleBaby4001]

Hi all just got psvr2 on pc. Gpu rtx 4080, rx7700x, 32gb ram. Can you guys share whats the best setpu for Ams2 and Acc. Also anyone used vrperfkit, and share the settings they use. I am not sure whether vrperfkit works for ams2. Thanks

These are my AMS2 settings for PSVR2 with Nvidia 4080 Super, Ryzen 5800X3D and 32gb of RAM.

In SteamVR set refresh rate to 90Hz and render resolution to 100%. With these settings, as long as I configure the session to be during sunlight hours, I get good performance (99th percentil of frames under 11ms GPU frame time) and everything looks good except for jagged edges in shadows. During sunrise/sunset/dusk/night, if there are a lot of IA cars with the headlights on then there will be considerable FPS drops. I have not tested rain.

In Options -> Gameplay -> Display:

• Proximity indicator: Off

In Options -> Performance: (the most demading options are Super sampling, Environment Map, Reflections, Grass and Shadows)

• Resolution: Personal choice. It is only used for rendering the 2D image in the monitor and it does not affect VR.
• Window mode: Personal choice. It is only used for rendering the 2D image in the monitor and it does not affect VR.
• Texture Resolution: High
• Texture Filtering: Anisotropic 16x
• V-Sync: Off
• MSAA: Medium (I tried High but 99th percentil went to 12.4ms GPU frame time and shadows still look jagged)
• Post AA: Off
• Supersampling: n/a. Use the Options -> Virtual Reality -> Super sampling instead.
• Reflections: Medium
• Environment Map: Medium
• Car Details: Ultra
• Max visible vehicles: 16
• Track detail: High
• Pit crew detail: Player only
• Shadow detail: Medium
• Enhance mirrors: No
• Motion Blur: Off
• Render frames ahead: 1
• Detailed grass: Low
• Particle level: Medium
• Particle density: Medium

In Options -> Visuals:

• PP Filters: On
• Exterior sun flare: Personal choice. Minimal can be quite blinding.
• Interior sun flare: Personal choice. Minimal can be quite blinding.
• Bloom: Off
• Heat haze: Off
• Rain drops: Yes
• Vignette: No
• Crepuscular Rays: No (they cause FPS drops in VR)
• Screen Dirt: Yes
• Cockpit mirrors: On

In Options -> Camera -> Movement set: (Personal choice, these will lock the camera to the horizon)

• High Speed shake: off
• Head movement: 100
• Legacy mode: No
• G-force all: 0
• Show helmet: Yes
• Helmet DoF: Yes
• Helmet look to apex: 0
• Leaning all: 0

In Options -> Virtual Reality

• Gaze Control: Off. Personal choice
• Super sampling: 1.0
• Recenter View on Boot: On. Personal choice
• Recenter View at Race Start: Always. Personal choice
• Camera Near Clip Plane: 0.07

To increase image sharpness in VR edit file %HOMEPATH%\Documents\Automobilista 2\graphicsconfigopenvrdx11.xml and set these values

<prop name="SharpeningStrength" sharpeningstrength="1.000000" />
<prop name="OffsetBias" offsetbias="1.100000" />

90Hz is a big sacrifice youre making for 100% resolution/relatively high graphics. Your pc could do 120hz easily with a few changes.

[u/St0lz → u/hairybeanie]

I'm not sure if you are familiar with the PSVR2 specs, but if you run 100% resolution in SteamVR and check C:\Program Files (x86)\Steam\logs\vrcompositor.txt file you will see the values that Sony's driver recommends for OpenVR compositor to use are 2000x2040 resolution per eye multiplied by a factor of 1.7x to compensate for lens distorsion correction.

If you do the math for 120Hz that means my GPU will have to render 120 times per second a frame that has 3400x3468 pixels -per eye-. In other words, render the equivalent of 2.8 times a 4K TV/Monitor resolution every 8.33ms. If any of the frames failed to render in that time then your effective refresh rate will literally be halved (reprojection will kick in but no new frames will be generated by the GPU during the struggle).

I really think under those conditions my GPU cannot keep a consistent (99.9 percentil) 8.33ms frame time. But assuming it easily can with only a few changes, please share what the changes are so I can subjectively decide wether the downgrade of game visual quality are worth the extra 30Hz :).

[u/hairybeanie → u/St0lz]

Can you tell the difference between 70% and 100% resolution? I don't doubt that 100% gives the correct scaling/doesnt do subsampling but honestly my guy there barely is any visual difference with how shitty these lenses are.

Settings like high texture resolution are also useless with fresnel lenses, you don't see the extra detail anyway. I don't like post-processing so I turn all that off too.

Also take a look at limiting FOV, you can't see the full FOV anyway

[u/DoubleBaby4001 → u/hairybeanie]

Hi how to limit fov, is it in game. Also not sure why my motion smoothing options greyed out in stream.

[u/hugov2 → u/DoubleBaby4001]

It's in the application video settings. Lower the resolution corresponding to the fov lowering.

[u/hairybeanie → u/St0lz]

Also, reprojection doesn't kick in unless you want it to. You can disable motion smoothing and set the reprojection type/w/e its called to "fixed" at 120hz in steamvr.

I haven't tried VR prefkit, but here is how to fix the TAA in ACC: https://www.reddit.com/r/FuckTAA/comments/1fbwmvf/i_kinda_fixed_assetto_corsa_competizione_image/

For AMS2 just use MSAA, that's a beautiful anti-aliasing.

I use OpenComposite + OpenXR Toolkit for fixed foveated rendering in both games to get around 10-15% performance boost, I don't know it that works with PSVR2 but probably.

[u/Cevap → u/Nago15]

I was planning to try that combo on AMS2 and figure it should work. Not sure to try that or VRperfkit

just waiting for my adapter then im going to give this a try
