badipaddress Posted April 10, 2021 Share Posted April 10, 2021 I've just noticed after reinstalling my Combat Mission titles on the new PC that I have a the letters "NO DC" written in the upper left part of the screen. I never noticed it in my old PC. What does it means? It is a minor issue but how I get rid of it (it is present also in the map during normal gameplay)? Thanks in advance! 0 Quote Link to comment Share on other sites More sharing options...
badipaddress Posted April 10, 2021 Author Share Posted April 10, 2021 Sorry, problem solved, it is not related to Combat Mission, it is caused by some strange NVIDIA GPU settings. I've tried to "restore" the default options in the "Manage 3d settings" in the NVIDIA control panel and the strange iscription disappeared. 0 Quote Link to comment Share on other sites More sharing options...
Thewood1 Posted April 10, 2021 Share Posted April 10, 2021 I had this issue in X-Plane recently and resetting the nVidia to default fixed it. There is some specific setting in nVidia that causes the issue with Vulcan and OpenGL APIs. On the X-Plane forums, there was a theory that it has something to do with Threaded Optimization. But I haven't seen that. The underlying theory is that the 3D program is forcing some kind of overlay or maybe suppressing one. I also saw that quite a few people see the issue return eventually. I haven't seen that yet. Just some background. 1 Quote Link to comment Share on other sites More sharing options...
