Performance/Quality Tweaking with Custom Resolutions

[Ralf]

This is a purely optional step to take full advantage of vorpX’s Direct VR settings optimizer. vorpX will still work fine if you can’t add custom resolutions on your PC.

What are custom resolutions?

Custom resolutions allow games to run at resolutions that are normally not available on your PC. Adding them allows vorpX to choose resolutions that are better for VR than your ‘normal’ monitor resolution(s).

Resolutions to add

Some of the resolutions below may already be available on your PC. You don’t have to add resolutions that are already there.

4:3	Narrow
1440×1080 1600×1200 1706×1280 1800×1440 2240×1680	1024×1080 1080×1200 1200×1280 1368×1440 1600×1680

Add custom resolutions for nVidia GPUs

1. Right-click an empty spot on your desktop and choose ‘NVIDIA Control Panel‘.
2. Go to ‘Manage 3D Settings‘ and make sure all ‘DSR Factors‘ are unchecked.
3. Switch to ‘Change resolution‘ and click the ‘Customize‘ button.
4. Make sure that ‘Enable resolutions not exposed by the display‘ is checked.
5. Click the ‘Create Custom Resolution‘ button.
6. Enter the width and height of your custom resolution in the according fields.
7. Click the ‘Test‘ button.
8. If the test succeeds, confirm the next dialog with ‘Yes‘.
9. Repeat steps 5-8 with all resolutions listed above.

Add custom resolutions for AMD GPUs

On AMD GPUs resolutions higher than your monitor allows will not work. If for example you have a 1920×1080 monitor, only add 1440×1080 and 1024×1080.

1. Right-click an empty spot on your desktop and choose ‘AMD Radeon Settings‘.
2. Switch to ‘Display‘.
3. Click the ‘Create‘ button next to ‘Custom Resolution‘.
4. Enter the width and height of your custom resolution in ‘Horizontal Resolution‘, respectively ‘Vertical Resolution‘.
5. Enter the width and height of your custom resolution again in ‘H.Timing Display‘, respectively ‘V.Timing Display‘.
6. Click the ‘Save‘ on the top/right of the page.
7. Repeat steps 3-6 with all resolutions listed above that are lower than or equal to your monitor resolution in both directions.

All this sounds pretty cool. So if I want to keep the same quality I have now in the rift, should I try the 1920 x 2160 setting? I want to keep the resolution as high as possible but save on the extra rendering if possible.

[NipOc]

If you want the same quality as before, you should choose 960×1080. Everything above that, has a higher quality (1280×1440, 1600×1800, 1920×2160…).

I tried this with Fallout 4 by setting the 960×1080 in the ini. It worked and looked nice but the HUD and cursor is unusable. Is there another trick I can try?

[NipOc]

Not all games support all resolutions, but you could try a 4:3 resolutions like 1600×1200.

[HKPirate]

Nvidia have DSR. can vorpx use this to get better quality ?
ETC. 1920 x 1080 (use 2X =3840×2160)

[Ralf]

Using a custom 8:9 or 1:1 resolution like described above is far superior as 1. no additional downsampling is involved, 2. it also solves FOV issues in many cases, and 3. it avoids rendering overhead, effectively enhancing performance.

The lock picking screen is missing with a custom resolution. I tried dishonored (g3d), outlast (g3d) and bioshock infinite (z3d). They worked perfectly with 1600*1800. The image quality was very nice.

I know i probably sound stupid, but how on earth can do you set a custom resolution in space engineers, also there is no optimiser options in the vorpx control application

[RAGEdemon]

Is this still Valid with v16?

I have a DK2, (waiting on CV1 to ship).

I have set the resolutions but when I go into the games, whether Geometry of Z-buffer, the horizontal line is indeed reduced but the 3D effect has disappeared -both separation an convergence.

Will this still be valid for CV1 which has dual screens?

[alegse]

3D effect does not work with all resolutions even if the game does load in VorpX.
For example in skyrim you can play with a 1:1 resolution (I played with 1400×1400) and it works BUT geometry 3D does not work unless I go to 8:9 or 9:8 (or standard resolutions like 4:3 or 16:9). So for geometry 3D I play in 1280×1440.
I am not sure about other games but this was the case for me with Skyrim

[wm79]

So the actual resolution in the Oculus CV1 will be 2160 x 1200 although I adjust it to a lower 8:9 resolution?
This guide confuses me. Could you update it to CV1? According to the date of the post the guide might only apply to DK2.

[Usvart]

I am confused, too.

-Why to adjust a lower resolution, when 45fps can be solved?

BTW: New recommended resolution for Full VR is 1280×1024 now, no widescreen res anymore.

HTC Vive – Game fps always exactly half of Vive's max refresh rate

Is 1280×1024 the highest resolution, that makes sense?

[Ralf]

The higher the resolution, the better the image quality. But 1280×1024 is the perfect compromise between quality and performance on a normal gaming PC with recommended Oculus/Vive specs.

Compared to playing games on a monitor high FPS are a lot more important in VR, so that should be the primary concern when experimenting with different resolutions.

[Usvart]

Ok, thanks!
