The original title was:
“A temporary (but free) alternative to the expensive 2080ti->3090 conversion :25% performance boost (pimax)”
(It has been edited by a mod I guess, for more clarity)
This is especially for simracing guys who use to play at the 90hz mode (Normal or Large fov), but it could also work for other kind of games.
No big secret here, nothing revolutionary.
Just something I wasn’t expecting and that changed my mind about the possible use of a 8kX for sim racing.
I use to play Assetto Corsa on my 5k+/2080ti (no parallel projection needed, well optimised for VR, good simulation, tons of content)
After being hooked by the 144hz mode with smart smoothing, (because it was so smooth), I noticed that without smart smoothing, it dropped sometimes to the 90 FPS area, and at 90 FPS it was jerky/stuttering.
This gave me a bad opinion about the 90Hz mode.
Then, because I wanted to test Large mode, I tested the 90Hz mode.
With pitool 1, 202% Supersampling, I managed to have a solid 90 FPS, and found out that finally 90FPS on 90Hz is also very smooth ! and the Large mode is a no brainer for sim racing (immersion ++; sens of speed ++)
But with Content manager+shader patch+SOL, it’s GPU demanding. it’s ok most of the time but if I put more than 16 cars, or on certain track mods, I have FPS drops, and get something in the 72-75 FPS zone.
And at this FPS, this is stuttering.
So this gave me a bad opinion of the 72hz mode for sim racing (because things are moving fast, it needs to be smooth).
You see me coming?
I finally tried the 72 HZ mode (which also has got the Large FOV), of course I was expecting a jerky experience, but the contrary happened !
I had a very solid 72 FPS on the 72Hz mode and after hours of tests on different tracks, with different cars, I found it smooth as hell ! I didn’t believe my eyes. honestly, in the end of the day I couldn’t see any noticeable difference with the 90 Hz mode (according to my memory of it), and believe me I looked hard.
Not only that but now I can put 24 cars and have a smooth and stable experience, no matter what, and this is in Large FOV.
Here is the irony :
90 FPS can be a stuttering mess (if it happens on the 144hz mode), while 72 FPS can be extremely smooth (if it happens on the 72 Hz mode).
-without smart smoothing, If you have less FPS than your refresh rate, you’ll have a jerky experience.
-If you have has many FPS as your refresh rate, the experience is smooth.
-a solid 72 FPS on 72Hz mode is smooth enough for sim racing, (tested at very high speeds, and on all kind of race conditions).
-72 FPS is 25% less frames per second to render than 90 FPS, hence a 25% performance boost that you can use for more cars, more SS, or more visual quality option.
Maybe if you go straight from 144 hz/144FPS to 72 Hz/72FPS, you’ll see a difference in the first place, but my point is that the 72hz mode is way smoother that what I expected, and more than enough for sim racing.
This is why the idea of a 75HZ max framerate on the 8kX in native resolution doesn’t bother me anymore when it comes to sim racing, as soon as you can get a solid 75 FPS.
