It seems that UT3 hasn't aged very well and it has trouble cooperating with newer hardware or drivers.
I'm running on this PC:
Mobo: Asus P8H61-M LX2/SI
CPU: Intel Pentium G630 2.7GHz (Socket 1155)
RAM: 6 GB DDR3 GoodRAM
GFX: Palit Geforce GT440 GDDR5 1GB
SOUND: ASUS Xonar DG
HEADPHONES: AKG K518; Creative Fatal1ty HS-800
KEYBOARD: Logitech K350 (USB)
MOUSE: Logitech G400 (USB)
OS: Windows 7 Ultimate 64 bit
I run the newest at the moment 320.18 Nvidia graphics drivers.

The main problem: Microstuttering.
During the game it's skipping 1-3 frames when I turn around quickly. It annoys a great deal and doesn't allow me to aim precisely. The GPU usage during the game is VERY low and perhaps drops down for a moment during the stutters, as shown in the pictures in the attachments/below, while the CPU is around 70-90%, even in menu. I've done all the tests on first campaign mission in singleplayer, since I'd like to host 4 player matches for my friends from time to time.
Doing the diagnostics by using the stat engine command in the console, it seemed that my input lag is abnormally high, sometimes jumping up to 90ms, though not always along with the stutter, along with the frametime jumping up to >=120ms along with the stutters.
Second problem would be quite low FPS hovering around 20-30 FPS in that very first tutorial mission when looking across the map.

What I've tried is:
Changing UseMinimalNVIDIADriverShaderOptimization, bSmoothFrameRate, OneFrameThreadLag variables between True or False in config file(s) inside the C:\Users\Anijatsu\Documents\My Games\Unreal Tournament 3\UTGame\Config folder (not the Default*.ini ones)
Changing PoolSize=158 under [TextureStreaming] to 300, 600, 1024, 2048 in UTEngine.ini
Changing vsync on/off
Changing frame limit for the UT3 executable inside Nvidia Inspector

What I haven't tried yet is:
Installing GPU drivers version 182.05 from 2009 for a single game that's come out in 2007 and was never properly optimized for PCs.
