VSync issues and fps

[Derek44]

Hi all, i have already used the search function but didn't find something all right for what i am going to explane

i have a r9 290 tri-x 4gb with an lg 144 hz monitor and on rf2 i use vsync and running on 143 fps
i set the radeon panel on 143 fps for raceroom too but if i turn on vsync the game runs smooth but fixed on 60 fps....

ingame i have the monitor settings on the right resolution and on 144hz

if i turn off vsync fps increase and are fixed on 120 but i see some tearing or microstuttering expecially if i have other vehicles near

solutions? thanks in advance for who can help me with this

Did you turn off VSync ingame? By the way, you should limit your FPS to 141 if you use FreeSync.

The question is:

Radeon set on 143 fps
Vsync on no stutter but only 60 fps
Vsync off fps 120 but some stutter

If your computer cannot keep a steady 120 fps the frames will fall back to 60 fps.
Nothing in between if Vsync is on.
CatsAreTheWorstDogs: There is also something with the cable quality.
And at least some years ago you had to have double HDMI to get 120 fps.

No Bruno, i think my post is not so clear at this point

My pc goes perfectly on 130/140 fps with rfactor 2 with vsync on...

On raceroom if i turn vsync on i have frames strangely stuck on 60

Yeah but actually I did understand this
But eventhough I have never been running with Vsync on - then I have read that if something makes it difficult for the PC system to keep above 120 fps all the time then the frames fall back to ½ (= 60 fps).
And searching around I found also something about the cable and HDMI capacity

my graphical card is connected with a display port not with the hdmi

so is a raceroom issue with vsync?

 

[BrunoBæ]

DP is probably better than hdmi
No at least I havent heard about special vsync issues in Raceroom.

 

[Alex Townsend]

Isn't it better to run v-sync off with a frame rate cap anyway?

Try to disable vsync in game and set iit n driver.

 

[Jens Roos]

Try set you Hz for the monitor to an lower value like 85 or 100Hz and see if it changes anything.
(or any of your monitor supported lower Hz settings)

 

[Derek44]

finally i solved the problem, vsync works well only in full screen and i was runnging the game in window borderless mode, thanks

 

[Derek44]

anyway, last night i had a race with the 911 r and when i have other cars near my fps fall down....a lot with vsync on and off too....with rfactor 2 this problem for me is very little compared to rre....tips?

You're probably limited by your CPU's performance. In certain situations, even fairly powerful CPUs struggle to keep the framerate above 60. Try lowering the detail (track, cars, visible cars), but I wouldn't expect a big improvement.

 

[Derek44]

thanks Martin , i'm understanding that rre is very demanding to cpu compared to rf2, didn't expect this in a dx9 sim.

 

[Case_]

It's in large part precisely for that reason DX9 is 18 years old at this point (yep, it's that old), it's not optimized for the current hardware and has a lot of limitations. Raceroom can really push it to its limits at times.

 

[Derek44]

in the other side i admire how nice the sim is to be still in dx9, the 3d models and a lot of tracks are miles better than rf2 when it was on dx9
