Frame glitch (sound repeat)

I've already posted this on steam but thought it may help to post here too.

Im returning to this amazing game after time off modding for another game, I now have a 3770 8gb with gtx 960 and 550 psu so it's not performance this time! Great fps.
The problem is a slight frame skip / repeat where it stalls for a split second and repeats the same sound twice, like a little frame freeze.
With my old 3gb 32 bit cpu I did not have this problem.
I have tried many things but it seems like it happens mainly when there is lots going on in screen but regardless of which visual settings I choose. It's not a big problem just a slight imperfection that I didn't have on old rig.
Thanks

 

I'm now using auto visual setting and it seems lessened and still looks great but it can still be heard sometimes when there is many cars around, fps stays a smooth 75 always, strange? :/

 

Tried adjusting all visual elements 1 by 1
Tried disabling afterburner, v sync.

 

Do you have a freeze on multiplayer when someone connect, or when an UI is first displayed in MP race?

 

Yes I have always had a slight freeze when players join, thought it was normal.
Sorry what is Ui?
Thanks

 

I want to optimise my game until I see fps drop, this sound repeat is happening way before any fps drop, it's annoying lol

 

Sometimes I double shift because It skips / repeats sound and the point of engagement

 

I can't see this as normal, never got this in any game, and regularly breaks my qualif time. There's also this freeze with displaying UI (User Interface, I mean HUD) while in race, generally around the end of first lap when others go though start line. This one can break my race if it happens in the bad moment. I reported this here.

I don't have your issue with sound only, all my freezes are related to player join or HUD display in race (from other players).

Maybe check that you don't have another Windows program using intensively your CPU every X seconds or minutes.

 

Okay thanks, yes it's a different problem, I don't get any freezes with the race update overlays at all, mine happens offline too, the more that's going on the regular they seem, I always open taskmananger every start up and disable everything that doesn't say steam, windows or nvidia.
Thanks

 

For example it even happens with less cars in wtcc, they seem more demanding.

 

Another example is I can make the same replay do the sound repeat problem and without the problem by altering graphics right up or down.

 

How many AI cars do you play against? Too much AI will generate stutters if the CPU can't handle them. Last time I tried the maximum AI on Nordschleife I had to reduce to 60 or so. ^^

 

I rarely use offline, just to start a race and test this glitch really, so going off the average online racers it's rarely more than 30 when I play at night, I test glitch at the back of grid with around 20 cars

 

Performance (fps) remains fine

 

It is not consistent it seems fine at times, other times when I'm not around anyone it has still done it, but it's definitely seems more so if you crank everything up and less with it all down, just want it gone.
