I've been using SAPT recently on a Russian MTA server where they have speed blur enabled.
Only issue has been, MTA re-enables the blur at the start of each race round, so you keep having to press ctrl alt m to get it to disable the blur.
I've found a way around this using a program called JoyToKey that took about 2 seconds to configure with a few clicks, then bam, I can use joy1 on my gamepad to disable blur.
Thanks again Slick for an awesome mod.
Anyone interested in getting JoyToKey, it's @
