Devs, what is the resolution slider *actually* doing?

Question :Pecho_Scared:

I want to have a better understanding of how resolution scaling ultimately works. I am using a Quest 2 connected by link cable, which means there are 3 different places for me to set resolution:

  1. In the Oculus software as a global setting.
  2. In SteamVR, as a global setting (resolution each eye, seems to detect what's been set in Oculus), and a per-application setting (a multiplier applied to resolution each eye).
  3. In ITR, as a resolution multiplier.

How does ITR's resolution slider and upscaling work with all this?

Let's say I have my settings as:

  • Oculus: 1216 x 1216 per eye (resolution slider at minimum)
  • SteamVR: 100% multiplier (detects 1216 x 1232 per eye)
  • ITR: 200% resolution, AMD FSR UltraQuality (internet says this is 1.3x, or 77% output resolution)

Does this mean:

  1. ITR detects SteamVR is set to a 1216 x 1232 resolution.
  2. ITR's resolution slider doubles that to 2432 x 2464 and sets it as the target resolution.
  3. FSR renders the game at 77% of this target resolution (1874 x 1897)
  4. FSR upscales the result by 1.3x (2436 x 2466)
  5. This 2436 x 2466 image is sent to the headset.

Is that right?

Devs said you’re pretty much spot on in your observation. Only thing to point out is in number 3. FSR renders at 85%, not 77%.

Ah thank you! I can see now in the INI files that ITR has its own presets:

fsr_Ultra1=r.ScreenPercentage 85
fsr_Quality1=r.ScreenPercentage 80
fsr_Balanced1=r.ScreenPercentage 75
fsr_Performance1=r.ScreenPercentage 65

I have another question. In the INI files I also saw

[taau]
taau1=r.ScreenPercentage 100

Does this mean that ITR's TAU doesn't do any low-resolution rendering? It skips my number 3 and goes straight to upscaling?
