I also consistently auto-dodge at the worst times. Usually happens more often when I circle strafe and hit the arrows keys very rapidly, but has occured at the drop of a hat on the edge of a walkway in Command, leading to an untimely acid bath. It occurs excessively while online on any server, pugs or pubs. Happens occasionally in a LAN game with ACE/UTpure/SmartCTF installed but no zp or NN. Does not occur in UT3 and I have not encountered any issues with any other game, which leads me to believe it is not my keyboard. Having said that, I have tried a few different keyboards and USB ports on my rig to completely rule out the hardware side.
If it is happening on almost every single key press a complete restart will usually help, but the problem comes back 5-10 minutes into a match, with varying degrees of severity. It seems to happen more in tdm, but my movements are also quite a bit more rapid and erratic compared to ctf. I use my strafing movements to line up a lot of horizontal shots and randomly side dodging (I would say well over half or more is a side dodge for me) just completely throws my shot off and usually leads to getting an ig beam to the face. This is not a random problem for me, I have noticed it for well over a year and have consistently whined and bitched and moaned about this issue, as well as rapid firing or not firing at all when respawning.
my rig at various stages, auto-dodging has occured consistently throughout upgrading
Mobo - Asus M4A78T-E
CPU - Phenom II x4 965 BE @ 3.4ghz (stock) - also was happening on an Athlon II x3 unlocked to a quad core @ 3.2ghz
GPU - Sapphire 7790 1gb dual-x OC w/ latest and greatest drivers - also was happening on a Sapphire 5770 Vapor-X
Keyboard(s) - old ps/2 mechanicals from the mid to late 90's and early 00's to brand new wrapped-in-the-box usb and ps/2 keyboards straight from HP - i get auto dodges using any keyboard
Mice - Razer DA 3.5g and 4g (2013)
Logitech g400x2, g400s, g500s, mx518 - I get auto dodges using any mouse with and without drivers
I have switched .ini's, renders, mouse settings, graphical settings, CCC settings, almost everything in an effort to get this to stop. I'm up for suggestions.
