Hi

While I keep the same pitool at 2, base SteamVR SS 20%, per App SS 250% (assetto corsa), no advanced supersampling filter, which makes a total SteamSS of 50% and a total SS of 50x400=200%,

this leads to a resolution that is not the same everyday.

One day it was 4828x3216, the other day it’s 4828x3116, and today it gives me 4828 x 2980.

In clear, the first number stays the same, but the second number keep changing and I have no idea why since I don’t change anything in the game.

I made a test with FPSVR to detect the resolution in game, and it gives the same resolutions I just stated.

Any idea?

**Edit:** **mystery solved**

it turns out it comes from the different **screen vertical offset value** I used in pitool that changes the vertical resolution.

with vertical offset at 0 Left / -0.5 Right I get 4828 x 2980

with vertical offset at -5.5 Left / -6 Right I get 4828 x 3344

with vertical offset at +5.5 Left / -6 Right I get 4828 x 3496

putting both vertical offset to the minimum -10 or maximum +10 gives me a vertical resolution of 3608

with both at zero vertical offset it gives me 2980

So, **using the vertical offset in pitool only to raise or lower the virtual screen can lead up to a 21% maximum increase of vertical resolution. good to know in term of performances impact !**
