Stuttering

Cote Dazur · Dec 2, 2013

Just took advantage of the rebate on GTR 2, while I can run Race 07 at full video setting, getting hight FPS, smooth as glass, I have constant stutturing with GTR2, even at medium setiing and my FPS are in the 90's.
Any advice as a particular set up to GTR2
My rig runs AC, DTM experience, witthout issues. Their is something special about GTR2!

The good old multicore issue i assume. ALT+TAB out of the game and use the process explorer to change affinity to ALL CPU Cores. Multicores bugs out on GTR2 engine despite the power... Doing this removes the locking thread.

Also, Use VSYNC. Preferably NVidia Adaptive, if a possibility.

Thank you Richard, tried changed affinity to all cpu's and no changes to the stuttering.

Vsync in game adjustemnt makes also no difference

You have high fps however? If you vsync, can you measure and see that it caps it to 60 or so?

I feel the ram is a bit on the low side as well as cpu. Can you force the sync in ati drivers?

Also, it is a mac there, so you may not rule out that as a source of issues.

When I vsync at. 60 it stays there .
Again I am fine with other sims some much more recent, so I doubt it is the rig.

My screen refresh rate is 85 hz, this is what I usualy use.
