Dear Trion developers,
please look for some possible optimisations applicable to Radeon 69xx cards. I've upgraded from a single Geforce 8800 Ultra to two Radeon 6970s and the performance difference is underwhelming. No tweaks (except for MainThreadCPU=0, which barely makes any difference, and VFXLimit=10 (which kills the way the game looks)) help.
Same goes for CrossfireX performance scaling. It appears to be around 50% instead of closer to 100%. Forcing AFR (Alternative Frame Rendering) pushes it closer to 100%, but why do we have to use 3rd party tools such as RadeonPro to fix this?
And the last but not the least, could you please add the option to enable Triple Buffering? Due to the massive FPS swings in Rift I get screen tearing when running around solo (>60 fps) without VSync and serious input lag in raids/invasions (<20 fps) with VSync enabled. Triple Buffering would eliminate all the input lag scenarios without any fps reduction (assuming the amount of video memory is sufficient). Once again, it is possible to force Triple Buffering using RadeonPro or D3DOverrider, but this is a non-native implementation and doesn't work very well.
