Playing Ghost of Tsushima and just trying to get the best settings for my machine and was suggested to use high preset with resolution scaling off and frame Gen on.
It certainly makes the FPS counter say it’s 60fps now when it would constantly dip to 40, but it doesn’t feel or look smooth at all. I can get 60fps without frame Gen in much of the game, and turning it off in those areas looks smoother and feels nicer.
I’ve never used frame generation in anything else before so I don’t know if this is normal or what’s going on. Would it feel better if I uncapped the frame rate and turned off vsync?
Frame generation can only guess the next frame based on previous ones and motion vectors so when you do something it can’t predict (press a button) it still has to draw that normally. As I understand it because of this the input latency is going to be the same as if frame generation is off it will just look smoother.
it will just look smoother.
That’s the thing, though; it doesn’t look smoother either. There’s this hard to explain jitter in the motion that I’m only used to seeing in games running 30fps or lower.
This is a pretty early look at the tech but what they saw was that input latency actually increases with frame gen turned on so maybe that’s wheat you’re seeing? They also noted that at a 60fps target the generated frames were much more noticeable, so maybe that’s what you’re seeing?
One of the big factors for how smooth something feels is frame pacing, as opposed to raw frame rate. 60fps with steady frame pacing can feel smoother than 120fps with unsteady frame pacing.
If your hardware is struggling (ie, its capping out at ~40 fps) then there’s a good chance those frames aren’t coming in at a steady pace. The frame generation tech can only guess when the next frame will come in, and try to insert a frame half way through, but if that next frame comes early or late you end up with unsteady frame pacing anyway!
I’m not sure if you can cap to 30fps and then use frame generation to get you to 60 - that would certainly be a way to get steadier frame pacing.
Vsync is often the culprit of laggy feeling. I keep it off unless I get distracting screen tearing. Typically with a high enough frame rate it doesn’t seem noticeable to me.
