Hi,
I have this issue that’s driving me super crazy. Basically, often, in scenes with high poly meshes, I get extremely high framerates, but any time I perform viewport pan, orbit or zoom, there’s very short but super-frustrating lag at the very start. Basically, for first half-second of pan, orbit or zoom, viewport sort of jerks behind the mouse cursor.
What is very interesting, is that sometimes, switching away from blender window and switching back to it fixes it, but just for a short amount of time, and it re-occurs later on again. So it is definitely not a hardware issue, framerates are great.
It seems like an issue of hit-testing or some random mesh evaluation.
Does anyone have a solution for this?
Thanks!
EDIT: Now this is EXTREMELY weird. The lagging stops as soon as I have 3ds Max running in the background, and returns as soon as I close it. It’s perhaps a problem of Blender being so efficient it puts GPU or CPU to rest when not doing any viewport interactions, and CPU and GPU then taking some time to wake up when I perform viewport navigation. 3ds Max usually burns some CPU and GPU time even when idle, so that may be it.
Again, any suggestions are much appreciated. The lagging is making me lose my mind!
