If I turn off "useOcclusionQuery" everything is fine and smooth. I'm using T3D 1.2.
Anybody know how to fix this?

I have a nVidia GTX 780M card with ample of memory.

Out of curiosity, do you see the same behavior in the 3.8 release candidate binary?

Also, how are you achieving your high speeds? Just a spectator camera set to max? In a vehicle?

Hi JeffR,

It happens when driving, flying, or moving the camera really fast in the World Editor.

I'm using 1.2 only. Never tried it on 3.8, as my project's majority features currently only work on 1.2. A port will be done later on after initial release. So, I'd like to have this work in 1.2 for now, if possible.

Oh, I totally understand, I just wanted to check if you could replicate the issue or not with 3.8's binary. That'd tell me if the issue was fixed at some point or another.

I'm not able to replicate it with the current 3.8 binary on my machine at max spectator cam speed, so if you could grab it from here and try to replicate it and see if you still get the stutter or not.

That'd let me know if it was fixed between 1.2 and 3.8, or if it's something with your system(particular graphics cards, drivers, etc).

It does it in 3.8 RC, as well. Very subtle, though. If you put the camera under the water, in a level with only water and terrain, and you move the camera upwards really fast facing the sky, you can see a small stutter/freeze. Same thing happens in 1.2. The more populated is the level, the more obvious the stutter gets. It only happens the first couple of times you speed across the level. It seems to settle after.

So it ONLY happens when underwater? Interesting.

: No, not just from under water. The moment the reflection of the water gets into view after being occluded by terrain, there's stutter.

That fix makes no difference. Problem persists.
