I have looked into 3d center forum as a reference on sli bits and such. But far as actual tuning and all the time spent on it, all done by me and boy some games took forever to tune, man your not kiddin. But yes I go to that site as reference, basically all the time. Excellent stuff there, Very highly recommended. And thanks for your kind reply. If anyone wants me to upload a particular game that I personally worked on, please let me know. This is going alot better then expected. Now working on Shadow of tomb raider, so far scaling is good. 21 fps to 76 fps with no flickering,etc, only problem is within the city in the beginning where there is lots of people, there seem to be MAJOR scaling issues from 2-way to 4-way, working around it. Speaking of which, Do you know how to shut off the pure hair?? I know the first game you can, this one you can't. Very annoying hair problems. Still needs tuning.
