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]

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?

It was really really confusing

The green bar is supposed to be almost full, that's normal. If you haven't already, I suggest you update to AMD 14.4 drivers, as some users have seeen big performance gains with those.

I have updated to that version and got no improve

14.4 have been excellent for my 7850.

However, I think you have cpu issues as you mentioned the purple line peaking.

I don't think I've ever seen that peak on mine - it's always been the green line that has been high when I had stutters.

Mate for a guess ur monitor is only 60hz by u saying it sorts it out when you have vsync on if ur monitor is 60hz ist pointless displaying much more than 60fps try to limit the fps to 60

Ive found a HUGE increase in rf2 performance after disabling hyper threading in my bios, tracks are loading faster, tracks that previously had laggy sections are now smooth and the micro pausing/stuttering has almost been fixed...almost, the only downside to this is a lot of my other programs/games seem to have taken a hit.
The things we do to make rfactor 2 run better

Hyperthreading provides no gain in games and can even hurt some games just a little. Hyperthreading is strictly for desktop apps and encoding.

yeah i saw a very big hit in smooth video project, i had to reduce some of the options as it kept giving me high cpu warnings. pretty sure i noticed reduced performance in both R3E and AC aswell though, always had very fluid gameplay in both those games and after turning off hyperthreading it just didnt seem as fluid.

edit: after doing a bit of digging on the interweb the consensus is badly optimised older games dont like HT'ing but modern well optimised games such as crysis 3 love it...not sure which category either R3E or AC fall into...rf2 definitely sits in the first category.

edit: also maybe windows 8.1 x64 utilises HT'ing which might also contribute to a reduction in overall performance that i noticed in other software?

No it isn't pointless, higher framerate reduces input lag, which is a very nice thing for racing simulators.

You can probably count on one hand with 3 fingers missing how many games benefit from hyperthreading, and even then you're talking a 1% gain at best.
