Game's motion running slow, but frame-rate is high

[Yukicore]

So yes, I have a problem with some games that frame-rate is 60 or above, but game seems to be running kinda slow, really weird, and I don't know what's wrong, I always though frame-rate and lags were the only visual performance drawbacks. I have this for 2 games, but I'm pretty sure they are not the only one's. (Those 2 games are - Prototype 2, Fifa 12 and maybe, just maybe, Mafia 2 (seems like the number 2 is cursed ))

Here is my PC hardware setup, all drivers are updated to the latest, Windows 7 64bit, as less as possible programs/applications, disks are defragmented, registry is cleaned, cache is cleaned. Any ideas?

CPU - Intel i5 3570K
GPU - Sapphire Radeon HD 7950 OC (Dual-X) (GDDR5)
RAM - Crucial Ballistix 8GB (1600MHz) (DDR3)
MTB - Gigabyte GA-Z77X-D3H
PSU - Coolermaster GX-750W
HDD - Western Digital 7200Rpm 32Mb cache

It might be stutter. The brain perceives motion from the series of images only when they are delivered in a smooth way above about 24 fps. More FPS is smoother but only if the distance between frames is consistent.

To test get Fraps and in the settings make it record frametimes. Go play your game, start the logging (hotkey from fraps) and play until you notice it stutters, give it a little while at the stuttering, stop the log and go view the file it produced. 16.6ms frame time is 60 ms and what you are looking for is near the end of that log for that frame time to differ frame by frame. You are looking for patterns of inconsistent times in about 60 frame chunks all the way down to small numbers of frames.

The ideal log would be 16.6ms right the way through, occasional jumps to 33.3 or other numbers can be perceived as little jitters but consistent alternation or patterns can change your perception of smooth motion despite high FPS.

I used to have 2x 7970's and I had a lot of stutter and jitter problems in a range of games, in both crossfire and not. I changed to Nvidia and I haven't had the problem at all. I feel your pain, those people who see these problems and are irritated by them will be very disappointed with AMD's 7000 series cards, but you often don't know you suffer with it until you see it.

Same thing happens to me in Diablo 3

V-sync off, 100+ frames per second, but it feels like a stuttery mess

V-sync on, 60 frames per second, and it is butter smooth

my intellect tells me the 100+ frames per second should be smoother/just as smooth as 60fps

I've read that only Crossfire and SLI suffers from stuttering, and also weird thing about this card is that when I played on consoles 30 frames seemed fine, acceptable and smooth, but with PC 30 frames is too low and games are unplayable @ 30fp/s, anything below 50 is unplayable. What about that?

Do consoles have some kind of frame smoothener-ish that makes them look more flawless and smooth?

Okay, from what I can see it's display refresh rate and frames delivered to it fault for you, with Diablo 3, but what I have is different. 70frames at one angle seems smooth, but from the other angle with same frames, it's stuttering. also you have SLI, which brings stuttering, as I mentioned before. And for Fifa 12 I have V-Sync enabled, and in option it has some option (which I have checked, tried playing unchecked, got even worse) which says that It fixes stuttering for ATi users.

Does anyone have more information about this? Is this an ATi problem or something? Because I haven't seen any compatibility issues with Nvidia cards, but with ATi there are.

Could be image tearing

 

[MrK6]

Take a video of it, if possible. Are you running at the stock clocks with stock voltages? Did you remember to install the chipset driver (very common for that to present like this)?

 

[Yukicore]

Nonono, not image tearing.
I am running @ stock clocks, except I have OC'd my motherboards RAM memory frequency from 1333 to 1600MHz, trough BIOS, it supports it. I have all the latest drivers, Chipset driver was one of the very first one's I installed.

I am not sure if in a video you will be able to see that, It's that kinda thing you can't spot in a video, especially compressed one.

I have no idea how to explain this issue, but let me put it like this. Normally when moving camera is silky smooth, but at some points when I am facing a different direction the camera movement seems more torn, jaggy and not as smooth. And frame-rates are almost identical 0-3 FP/s.

This is not a glitch in my head or eyes I am sure.

Do consoles have some kind of frame smoothener-ish that makes them look more flawless and smooth?

Consoles are working against known hardware, so game performance can be extensively profiled and adjustments made to keep frame render times near 33ms/16ms. So that helps smoothness a great deal right there. But console games (particularly the 30fps variety) are also notorious for bluring frames together (temporal reprojection) to give the illusion of fluidity and smoothness that doesn't really exist. So there's both a component of real smothness and fake smoothness in many console games.

Until you do the test and have some data we can't be sure its not just the basic stutter problem that has plagued AMD's 7000 series since launch.

Stuttering can and does affect single cards, it occurs in certain poorly written/ported games that stack up lots of frames from the CPU.

OP: You Sir, need a 120Hz monitor

 

[Yukicore]

Yeah, that's what I thought, thanks, ViRGE.

What test and what data, can you please be more specific? I think the Prototype 2 definitely uses a lot of CPU power, but I have a very powerful one, so it shouldn't be a problem, right?

I sure do need a new monitor, because I hate my current one, it's 1080p and looks good, LED backlit with good response rate. But it doesn't automatically turn off when there is no power given from HDMI connector, my Video card when it's off it's off, and monitor thinks as if there is nothing connected to him. And that's really annoying. Colors are great, looks sharp. But I'm scared of getting a worse one.
