It is possible...So soon after release ? maybe...

Luthier said the filter makes lower- spec PCs lose about 10 fps...
So if this is mid- spec PC is running at 30 fps instead of 40 fps, it isn't changing a big deal as we watch it on Youtube...I read one russian post where the guy had pretty poor fps with 2 GTX570 SLI...Then he disabled the SLI, and his fps jumped up by 2.5 X...He was quite happy...
What has to be in the game : SLI/Xfire compatible, multithread efficient, and 64 bit for maximum memory usage...Then I'll buy it...
After that, there will be patches for optimisation and new features...

Salute !
