Optimal fps cap for frame gen?

[albanshqiptar]

Watching the DigitalFoundry video on the optimal way to setup your game for frame gen to be smooth, they mention that your should cap the fps of the game to half of your monitor hz rate.

How do you do this if you have a monitor that is higher than 120hz? Most old games at best have a max fps of 60. Does that mean if you use frame gen on an game that can't exceed 60 fps, it won't be as smooth?

Anything that can cap your fps e.g. ingame settings, GPU control panel, Rivatuners etc.

For games that have max of 60 fps, no cap needed if you use x2 frame gen then you should have 120 generated fps, provided your GPU has head room to do that.

It's best to also set the monitor to 120hz then for sync and frame pacing reasons.

i was thinking it will work ok (need to test myself:P. I have 180 hz monitor and i think with 60 lock it will work ok), but if game doesnt have 1\2;1\3;1\4 vsync you always can go to nvidia panel or amd and lock it there or use thing fro DF video (forget how it called). Reply to me if you test it and find something interesting.

My bad, I misread that he had a 120 hz monitor.

And what about vsync settings? For FSR 3 frame gen, you get best results when disabling vsync in game and enabling it through the gpu control panel.

Well, I personally don't use v-sync for capping fps. V-sync has its own performance impact.

Yes, that's the vsync settings that I use for many years now even before LS.

For any frame gen, I will turn off v-sync in game.

Alright. So if you're on a monitor that is above 120hz and you play a game that is capped at 60 fps, you should change your refresh rate down to 120hz?

My monitor is 165hz so the only options the control panel shows is 165hz, 100hz, 60hz.

[Rivaldman]

If you don't want any tedious work, you can try it with 120 fps on your 165hz monitor first.

If you find something not right, you can use external tool to give you 120 hz.

That's unfortunate. Well, maybe you will be happy with the result of a 60 -> 120 on 165hz, if not set it to 100hz with 50fps framecap, or use CRU (Custom Resolution Utility) to add 120hz to monitor.

Thanks. I now see 120hz as an option.

Hey how do you CAP with rivatuner or GPU control panel? Whenever I do either of those things it also ends up capping the FPS on lossless scaling, this not only makes it not work, it straight up breaks the app.

Don't use a global framecap, add an RTSS profile for each game.
