Did you done other tweaking on SWTOR or Windows 8?
None outside of the cursor lock program. Out of habit I've ran the normal icon too. Only issue I had with that one was cursor going to monitor 2 then a click there minimizes the game. When in combat, not pleasant to say the least to wait on the spinning wheel to find myself dead.
Right now I am seeing how far I can OC my CPU. Last night I played for like 7 hours nonstop doing things then finishing up the HK51 arc on my IMP character to see if it was different then the REP side. So ran the ship mission (THEO), the gathering missions, the 2 FPs then it was time for maintenance so logged out.
As a matter of fact, yesterday I installed TOR on my laptop with 8. I first installed the CE disks to save download time then patched up. Went right in and played.
