The FPS is high but the display is veryyyyy not fluent.

My CPU is i5 4570 and my GPU is AMD HD 7850. How could this happen? I got 100+ FPS and the video is still torturing me... what can i do

 

[kimisecond]

updated the Catalyst to 14.4 beta and got better... Just a little...

 

[kimisecond]

Have you tried running with the graphics/cpu monitor on (Ctrl + C) to see if the physics (purple line) or graphics (green line) peak at the point of the stutters?

Post your graphcc settings.

Hey guys, these are just a few things I tried with some success when I've had Micro-stutters with my Nvidia cards. I too had them in various titles even though my FPS were quite high. Of course, you may already have tried these and I apologize if these seem redundant for you.

• Limit FPS using the in-game limiting feature where possible.
• Try a different Pre-render Frames Setting (not sure what it's called with AMD) This can be found in your Video Card driver settings
• Try turning off one video feature at a time and testing. It can often be just one setting that is the cause.

That's the graphics peaking (green line)

which drivers are you using for your nvidia card? ive been fighting with micro stutters all year, it seems random for me, sometimes i can fire the game up and it runs like silk other times i get constant micro pauses. i7/gtx780 combo. Ive tried all the plr tweaks i could find

337.50beta, I read about it in a spanish site, pleople talks about great improvement, and I´m trying it.

LOL, I was about to post my findings after I spent all of last night and several days prior trying to get it to run smooth. I have a Nvidia GTX680M, using 331.40 and using the trial and error method, I have come to the conclusion that it is a little bit engine problem, but mostly video sync IMHO. I have tried limiting,turning off, splitting settings(video driver) and I do get a little more FPS, but it still stutters. Best thing that has worked for me is, turning off anti-aliasing, FXAA and anisotropic filter in game and set the NVidia control panel with 16xAF, 4x anti-aliasing(could go lower)and FXAA on. But the main thing that worked was setting the VSync on in the control panel and selecting GPU VSync in game. I think the VSync was the problem for me and for the most part, it's easier on the eyes. I wanted to add, I am also using SweetFX on high.

The interessting bit is the one with the .plr file entry :

Steady Framerate Thresh="0.00100" // Allowed threshold in seconds to try to 'catch up' when falling behind using Max Framerate (use 0 for original behavior). This helps steady the framerate but may introduce more latency.

I tried it and it seemed less smooth. I upped the max frame rate to 100.

Maybe I shouldn't buy this 7850 and choose GTX 760...

 

[kimisecond]

That's the graphics peaking (green line)

seems that it only got high when i press F12... Usually gets three-fourths

 

[kimisecond]

I'll try to use catalyst settings to override the game settings... seem to work at this time. I tried to use "toggle AI" to test and everything is ok. Everytime I drove it myself it stuttered...

The pink line gets high when it begins to stutter. The green line just goes well.

yeah i suspected my ssd was the problem but after 3 reformats, one back to standard hdd, ive discovered the ssd isnt the issue, I guess its just an incompatibility that exists with my hardware and rfactor2 as EVERY other game is A OK. I can run with everything on low or everything on max and still the random stutters occur. ive tried various drivers/PLR tweaks/dll files, you name it ive tried it, and just when i think ive solved the issue i get a launch of the game that has the stutters. I can then shut down the game and reload and the stutters could have gone or could be still there, its that random...VERY annoying

edit: case in point, i rebuilt my machine last night and placed into another case, clean install of win 8.1 x64 nothing installed but rfactor 2, my gfx and t500 drivers, 3 launches have been smooth and 2 have had the stutters, nothing changes from the smooth launches to the stuttery ones, ive kinda given up trying to work it out now as i honestly dont see that its something i can fix,

Ok I got the same situation like yours. I got ALL LOW graphic settings and still MASSIVE stutters. Does HD 7850 get such a bad performance?

The pink line gets high when it begins to stutter. The green line just goes well.

Then this is the issue - your cpu is not fast enough (The pink bar should not go beyond ~80% or it can start to stutter)

Try reducing the amount of AI cars or close other processes that have a high cpu usage

My Cpu is i5 4570 and i dont think it has any issue... I ran test day mode and no AI added...

 

[Dennis]

well when you say the pink bar (=cpu usage) peaks whenever there is a stutter, then it is the cpu
How much cpu usage do you have when idle/in windows? Can you keep task manager open while driving and tell us how much cpu usage it shows?

ok i got a full reinstallation and this time , despite my PC couldnt recognize my Saitek R660, with all low graphics, CPU usage is fine now, but the green bar is full all the time... OK I will wait the next update... got to get my wheel back...
