Don’t think anyone here is getting rock solid performance atm.Users with the latest and greatest hardware specially cards with enough vram are probably getting a decent experience but maybe not where it should be atm.
Try the High end preset.Two major things are causing stutters on my system.Texture resolution set to Ultra.Terrain LOD@200 both combined I have heavy stuttering. Now I have less stuttering with texture res set to high and I kept my Terrain LOD@200
What drivers are you on? I found the latest one is not stable. Currently on 457.30.
