What is the actual cause of people seeing FPS different than others?

post #1 of 30
Thread Starter 
Is it an anatomy thing on a case to case basis? You'll hear people say 30-45fps is perfectly smooth for them, and yet if I ever drop that low in games(hell as soon as I drop under 60, even if it's 55fps, the difference in fluidity is extremely apparent and it just becomes a stuttery mess.) 30-35fps is absolutely unplayable to me, to the point where my eyes would hurt. 40-45 fps is ok, still very noticeable stutter, doesn't feel/look good but it doesn't give me eyeaches. So does aybody have a proven answer as to why this happens?

expectations and standards. Some people have just gotten used to low frames and find a certain threshold to be acceptable. It's not any sort of physical difference, it's just a preference.

Low fps should not give stutter. Less fluid but not stutter. Thats just bad GPU drivers.

From my experience it depends just on what you're used to. If you would game 2 years at 30 fps you wouldn't notice it anymore but 60 fps would be a mindblowing experience after that.

Edit: @ZealotKi11er sadly some game engines just are stupid like that.

Keep in mind that not everyone uses the word stutter in the same context. I've noticed that a lot of us have been giving it a very niche definition, which you just described. Poor GPU performance.

Ya'know I did hear something about Nvidia sacrifricing frametimes, for higher frames(or something like that) in their newer drivers. I am currently on 313.96. Would you recommend me rolling back to a specific set? Also now that I think of it, it really depends on the game that I notice the stutter with lower framerates. Crysis 3 beta for example, felt leagues better even when I was at 40 fps, when compared to any other game I would play at the same framerate.

Also, an occurence that always perplexed me, was that my laptop with an HD 4650m GPU would feel smoother at lower frames in comparison to my desktop. Even at 30-35 fps, it wouldn't be stuttery, it would just be "slower", less fluid as you've said. So I guess AMD has it right with their drivers while Nvidia...I don't know what they're doing..

I honestly don't know what else I could call it. It really does feel/look like a very obvious stutter/jitter. Even some games when I'm above 60 it appears(but doesn't feel) to have a jitter, but I've just assumed it's the tearing I would be getting that gives off that impression.

If you have Far Cry 3, try setting your vsync to 2 frames so it caps you at 30 and tell me how that feels to you. It looks/feels absolutely horrid to me. I'd doubt it looks/feels the same on the console version of Far Cry 3 or we would've heard how it's a jittery mess on there.

For an fps yes, anything under say 60 fps is very uncomfortable to the eye. but anything above 40 fps is perfectly playable, and your eyes can easily adjust to it.

That's backwards. It was AMD that was doing this and TechReport called them out on it and started a huge kerfuffle between red and green team in the forums and then AMD came back and was all "Uhhh, you got us, we'll fix it" but so far it's only been addressed in three games. rolleyes.gif

As for frametimes and what is acceptable, as long as your frametimes are consistent, it's fine. When you have Vsync on and are going from 16.67ms to 33.33ms every other frame for an avg of 45FPS, that feels bad. But if you have Vsync off and are getting a consistent 22.22ms frametime for an avg 45 FPS than that is fine. So long as the tearing is not too bad obviously.

That's just the thing. I NEVER have vsync on. Only game I have it on for is Far Cry 3, which somehow got rid of the stuttering that is synonymous with the game and still hasn't been fully fixed.(adaptive vsync specifically). In all my other games, if I was to be ~40-45fps, it would feel "ok" when moving the mouse around(responsive), but look very stuttery.

Yea exactly, its what you get used to. I gamed several years on console (PSone, PS2, XBOX360) and I thought GTA-games were very smooth (~30fps+occasional drops), now that I´ve played BF3 for some time @ 72Hz/72fps, drops to 60-65fps feels mehh in multiplayer-games, like BF3, CSS, in SP-games 50-60fps is still perfectly fine, cant stand 30fps anymore though frown.gif
