Just recently I have been having a problem with the Steam overlay whenever the RTSS overlay is active. What is strange is that it works fine in some Steam games, but in others I am able to get either the RTSS overlay or the Steam overlay but not both. The current issue I am having is concerning a game called ARK: Survival Evolved. Up until the last patch everything worked fine but now as I said, I am unable to use the Steam overlay when the RTSS overlay is active. I have tried Custom Direct3d Support and Stealth Mode, and neither makes a difference. Even when I disable the On-Screen Display the Steam overlay will not work. The Steam overlay will only work when I set the Application Detection to "None" for ShooterGame.exe. I have tried both RTSS 6.2.0 and 6.4.0 with the same results.
