I recently installed TOR on my bootcamp and I am experiencing low FPS, usually in the range of 5-15 with V-sync off and all settings on the lowest possible.
15" Mid 2010 Macbook Pro
Nvidia GeForce GT 330M (512 MB)
500 GB 7200 rpm Storage
4 GB Ram 1066 MHz DDR3
Intel Core i7
2.66 GHz Dual-Core
1680 x 1050 Resolution
I always run the most updated Bootcamp, though I have never updated (and never to be updated) Windows 7 Home Premium 64-bit.
My bootcamp partition is 50 GB, with TOR installed I have 7.15 GB left.
I recently played Rift on this bootcamp and also experienced lower then expected performance (though not as severe).
If anyone has any suggestions let me know!
