So how's the mouse accel emulator? Perhaps I could use it in UT4.
It worked well for what it did, high customizability. You could definitely use it for UT4 and the like.
Is not cl_mouseAccel enough?
Using extra program that may add some input lag. :s
That program was tested and didn't add input lag. Furthermore the accel curve is customizable and not set. So you can make it more predictable or use it only for flicks but have same low sens for aiming. Lots of options. You can make it a lineal accel curve instead of the usual crappy exponential one. All things considered it's a good option for those who want mouse accel.
For me it was just a test, and I've gone back to normal. Currently just using 800 dpi and 2.5 sens in the game without accel. But it was a good experience and if you're into accel I can recommend the driver.
