I'm not a programmer - it's just a weird idea. Please don't blame me too much!
WildStar does not support Reshade at all. But there is FXAA feature in Nvidia drivers and it always works correctly even in these type of games. So here is my thing:
1) is it possible to inject Reshade while using a method similar to the Nvidia FXAA injection (i.e. similar to Nvidia driver) but without active Nvidia FXAA? Maybe hook it to driver itself, or to the Nvidia FXAA injector and "just" suppress/replace original FXAA shader.
2) or (if it is impossible to suppress/replace original shader) with active Nvidia FXAA... i think it's still better than nothing.
