Games not smooth despite 60+ FPS when vsync is off!

post #1 of 8
Thread Starter 
When i bought my PC and installed a windows 8.1 for the first time games worked perfect vsync on or off. Then i got my HDD (Had SSD only before) and reinstalled windows 8.1 on SSD. When running games with vsync off they looks terrible. My fps is showing 60-120 (in most cases 80) fps, but games are not smooth at all. But when i vsync is on and games are capped on 60fps its smooth as butter! I dont mind playing at 60fps but demanding games as Dying Light , Far Cry 4 get those small fps drops to 57-58 that drives me crazy. My fps on these games is always around 80fps at ultra but does not feel smooth at all with that vsync disabled.

What could cause these problems?
My drivers are updated , Windows 8.1 is up to date as well. I dont have a virus.

PC :

GTX 970 4gb OC
i5 4690k
8gb of Corsair Vengeance 1600mhz
Gigabyte Z97 Gaming 3 Motherboard
Corsair x600m
Samsung Evo SSD 120GB
Barracuda HDD 1TB

What monitor do you have? Running above your monitor's refresh rate makes it tear like crazy which I know for me makes me motion sick.

Like i said , i played these games before smoothly on same pc and same monitor with 60-120fps. It seems that everything went to hell when i got that HDD and reinstalled Windows 8.1 . But i dont thinks that HDD is a problem, cause im running Windows 8 on SSD same as Dying Light. Also i did tried to reinstall Windows agan , but that did not helped either.

Anyway 60hz monitor , but im sure has nothing to with that, tearing is fine , i dont care about that , not smooth gameplay troubles me.

Its because of improper frame pacing. Because your frame rate is so high and fluctuates, the GPU improperly displays the frames in correct sequence.

So while you're still getting 60 hz, the frames could show up as frame 1, 2, 2, 3, 4, 5, 6, 6, 6, 7. Still 60 fps, but not paced correctly, giving stutter or unsmooth motion

The 60 fps frame cap with vsync usually correctly paces frames so you get them in the correct order, 1, 2, 3, 4, 5, etc.

I always play games with vsync and 60 fps cap.

Before I had G-Sync I ran v-sync on and tailored the detail lvl to ensure 60FPS minimum.

I also always play games with vsync at 60fps. On my screen and hardware if I don't, the screen tearing just gets way too annoying to deal with. To my eyes, 60fps is also silky smooth so it's an added bonus.

How do you deal with the input lag though? After moving to GSync 144Hz, Vsync 60Hz feels so juddery and sluggish (especially mouse movement). Like moving through molasses. You should really try a high refresh rate. You'll quickly find that 60fps isn't smooth at all.

I have a crappy 10+ year old mouse so the input lag isn't really that noticeable to me anyway. I also don't really play fps games any more that would require precise, fluid input. No idea what gsync is. I did a quick google on it and it appeared to be some kind of nvidia thing? (I have an AMD GPU)
