So i recompiled the VXGI branch and made sure to select NO when asked to overwrite files during compile and it worked!
I only get like 2fps in the Sci-Fi corridor and i can’t tell much from the cube so i will probably just wait for my new MSI GTX 980 TIs to get before i start running tests with it in one of my current projects.
I am going to try and recompile Flex now as well and see if it works.
