Frame generation in FPS games question

[Hume]

Hi, I'm on a 3840x2160 monitor using a 1080ti GPU, so far most games work basically prefect when I switch resolution to 2560x1440, but then I have to use upscaling like FSR to make it look better which can have varying results depending on the game. So this question is specifically for Cyberpunk 2077 and my setup:

My monitor only supports up to 60FPS, and I'd like to try Frame Generation for a change. However, I seem to be a little confused about how to use it. My understanding is to set the game, in my case, to limit FPS to 30FPS and then use this program's Frame Generation like LSFG 2.3, I'm guessing? With the mode set to 2x? I've tried this in some games but either see no difference or I seem to have some delays or something. Can anybody maybe advise me on what I'm doing wrong or what the supposed setting should be for my setup? I would really appreciate it!

I just want to try it out instead of just defaulting to using upscaling.

Yes, 30fps cap with x2 framegen, try both performance mode on and off. You can keep the monitor resolution at 4k, then set CP2077 to 1080p Windowed, in LS set scaling mode Auto and scaling type SGSR to bring it back to fullscreen. And try a lower LS resolution scale setting if you need more performance. Check your GPU usage, try to keep it below 90% for a better framepacing and less delay.

Thanks, I have no performance problems on High settings simply using ingame FSR or using this program with resolution tuned down a notch to 2560x1440 and then using upscale. Just wanted to see if it's at all possible to get away with full resolution but using Frame generation instead. But I'll try these exact settings soon.

The frame generation needs quite a lot of GPU power, the higher the input resolution, the more power it need. If you wanna run the game with LS at 1440p or 4k then try a 75% LS resolution scale for 1440p or 50% for 4k, so the frame generator gets a 1080p image.

Holy cr@p I just tried exactly this with a game, no upscaling, having the game at full resolution, which is 3840x2160, limiting game framerate to 30FPS, then enabling LSFG 2.3, 2x mode and resolution scale set to 50%. It works so smoothly and I do not see a downside to the resolution itself like with using upcalling. Is this how it's meant to work? So using this it seems to be possible to skip the whole lower resolution and scale back up?

Yes, it all depends on the game and the GPU. If you haven't done that yet try your settings in very demanding areas like Dogtown and Corpo Plaza, if it works fine there, you'll get good results everywhere in the game.

Ok, I haven't tried it with CP2077 yet now since I have to install it again but I did try it in 2 other games, and in both the performance is amazingly smooth now except I'm getting strange flickering things when things move, like, for example, I tried it now with Sniper Elite 5, damn is it nice now, but your character's head flickers when you run around. Is this maybe some kind of known issue when using Frame generation incorrectly somehow?

That's "normal" with LSFG2.3 in third-person games, you would need a much higher input framerate to mitigate that a bit, which you can't do because you only have 60hz. Try LSFG1.1 instead, but it has no resolution scale slider, so it's going to hit your GPU hard doing a 4k framegen. It's probably going to work ok at 1440p performance-wise.

Well, that is a sad problem. The entire idea for me is to not have to lower resolution (and then upscale again). I'll see how LSFG 1.1 works then but it doesn't seem to be a good thing to do to the GPU.

Edit: Tried 1.1, it does the same. I suppose I got too excited too fast, seems like upscaling may just be what I should keep doing, or at least case by case. Thanks for your help though, at least I finally learned how to use it even if it doesn't seem to be a fix-it-all-one solution for me.

Yes, and there's nothing wrong with that. "Native resolution gaming" is truly old-fashioned since the advent of FSR/DLSS/XeSS or similar.

You're welcome :) And once you have a 120+hz monitor you'll appreciate LS much more.
