Frame pacing problems - stutters

[nebej]

I dont see any stuttering in the latest video you uploaded. The red line (frame milliseconds) seem to be stable and the white line (which represents frame drops) never shows any drops.

My guess is that it is a problem with the terrain mega textures on your graphic card. I will make a special exe that disables mega textures that you can test with.

Looking at your hpl log there seems to be a new driver available. You could test it and see if it helps

I did not see any stuttering because i wasnt playing it in 60 fps. When running it on chrome i can see drops in the begining.
Downloading the movie and going frame by frame shows that the same frame is shown 2 frames in a row

Do you have <Engine LimitFPS="true" ../> in the config file?
