Warning: Microsoft DirectPlay has been deprecated. Then I go to Microsoft website and I find this: I checked in: 'Control panel/ Programs and Features/ Turn windows features on or off/ Legacy Components/ Direct Play', and the box is ticked! So what can I do now? I tried to untick and tick again, but nothing changes. Recently I updated my graphic card drivers (NVIDIA GeForce GTX 780) though GeForce Experience, and the problem with lag on full screen is back! The first time this happened, I didn't know what to do, but then running an old GM8 game Windows displayed a message about installing Direct Play. The games run fine in a window, but on full screen there is a serious lag, with constant micro-stops every few seconds.
I never experienced this problem before until I upgraded from Windows 7 to Windows 10. I use Game Maker since years ago, first GM8 and now GMS.
