From time to time I setup/install, play, then uninstall UT on various pcs in years.
I installed UT again a couple of weeks ago. v432. I was playing multiplayer without online session. All characters are computer except mine/player. It was working fine until a couple of days ago. However, a couple of days ago, I opened UT and at the start of game ALL characters including me/player were moving SLOW, even in running mode, which is default for me. And it's the same since then, moving SLOW.

Also, any movable object, loading rocket launcher for alternate fire, flight of rocket missiles after firing, jumping, thrown pod's motion etc. all are SLOW for all characters.
Edit: Gameplay is smooth but slow wrt player. Sound has no problems.
I tried some not all different game styles, CTF, Domination etc. with some not all built-in maps, but it's the same. ALL characters, moving objects move SLOW.
I don't know how to express this fault in other words. The motion of player, characters, objects is SLOW.
Edit: UT currently running on:
HP 6510b notebook
intel mobile GM965 Express chipset
Core 2 Duo T8100 2.1GHz
4 GB RAM
Onboard/i865 gfx
MS Windows 8.1 64bit
Kaspersky Total Security since pc first set up
Any ideas?
