OK, I get a different answer every single time I post this question. Can we PLEASE get a concensus of exactly what this function is responsible for? Here's the supposed "application use" list of answers I've gotten in just the last 36 hours: ATI hotkey poller does one or more of the following: 1. Hot keys to switch profiles easy. 2. Needed to run ATI overdrive. 3. Needed for vpu recovery to work correctly. 4. Removing it speeds up the system and now no more slow downs. 5. Removing it slows down all the functions and games take longer to launch. 6. CCC will not function correctly without it. 7. CAT AI is 100% dependant on it. Let's get some ATI people in here to finally get a complete answer on this. Thanks!
