Not sure if anyone has experienced it but there's been a lot of complaint as to the problem with DPI and sensitivity settings to cause negative acceleration in CSS, anyway it's now been fixed by using raw imput which is a for me. Back to full DPI i go! source:
What DPI and sens (in game) are you running? Oh btw just to make clear, the fix is only in BETA at the mo
Yeah that's high enough not to get affected, people who get it are running usually under 1.0 in css or dpis like 3200+
