Refresh rate question

[Ashen]

I'm struggling to run a certain game at 60 fps... Does that mean I'm forced to set my refresh rate at 60hz and limit my framerate at 30 fps?

I read that I must cap my fps at half my refresh rate for it to work properly (when using X2). My only options are 60hz, 120hz and 144hz on my monitor. I can't get a stable 60/72 fps (half of 120/144hz) in-game.

Can't I just cap it at like 50 fps and get 100 fps on my 144hz monitor? Just trying to understand :)

You can do that, but there's a chance that the frame pacing/sync won't be good, try it out. If you don't like the result try it with a 40 framecap and use x3 framegen to get it to 120fps, set your monitor to 120hz then.

I don't want to use X3 because there's too many artifacts. Assuming I want to use X2 only, want good frame pacing and no additional input lag, locking the framerate to 30 to get 60 fps is my best option, right? Unless I want to lower resolution and upscale to gain some performance.

That's matter of taste. Try it. You already get around 50-60fps without LS, some people prefer that to a 30/60 with framegen, some don't.

The most elegant solution would be to use CRU (Custom Resolution Utility) to add an additonal custom refresh rate to your monitor, so that you could get something like 80hz for example with 40 framecap.

I was in the same situation as you. I have a 144 hz monitor. My base framerate was dipping below 60 fps too frequently when capped at 60 hz and this caused a judder effect when using 2x mode with my monitor desktop framerate set to 120 Hz.

I then changed my desktop framerate to 144 hz, capped the framerate to 48 hz(144/3) with RivaTuner and used the 3x frame generation mode instead. Dips below 48 hz is much more rare so the 3x ratio is stable most of the time. V-sync is a must have for the best result. I have v-sync turned on globally in nvidia control panel. I also don't use the v-sync option in the app as it does not produce good results on either of the settings full, 1/2 or 1/3. I also have "allow tearing" turned for reduced latency and because I have v-sync turned on no tearing exist anyway. Using any other cap than 60 hz(2x) for 120hz or 48 hz(3x) for 144 hz result in judder. The idea is to keep the base frequency as stable as possible and match it with one of the monitors supported higher frequencies and use v-sync(not app) to prevent tearing.
