Hi, Update from my side:
Inside the Radeon Software I just tried to "not overwrite" game-specific preferences.
Additionally I removed "Steam overlay" for RB6 Vegas 2.
Done that I tried it and...no crash.. I play around and keep you updated (if someone is interested)
I also keep you informed whether it's the Radeon Software or the Steam Overlay. Currently I hope for Steam
The driver had his "overwrite game settings" activated. There were, afair, two options where the Driver overwrites the gamespecific stuff.
If I tell the driver (Radeon Software) to take whatever the software is giving then ReShade works.
Steam Overlay is active again.
So, dunno whether I'm the only idiot with that problem - but as troubleshooting this could help
