Choppy when moving and turning at the same time

Everything seems choppy when moving and turning at the same time. When I’m still, turning while still, or moving around without turning at all, it’s smooth as it normally should be. Never had this problem before.

Help?

I get that when I go into host_timescale less than one.

I have the same problem.

E8400
4870
4GB RAM
XP 32-Bit

I think I’ll just backup my addons and then reinstall.

Will update with result.
