Hey guys,
I am building the sample code for the green circle with vsync enabled (both in code and nvidia tool). I am using arch linux with newest driver and sfml distributed by the package manager. The problem I found, is the difference in frames I get, dependent on being in fullscreeen or not. This monitor can reach 144 fps and this works fine for windowed mode. But if I put the same code into fullscreen, it is locked to 60 fps. I checked it by using a coded fps counter and also the nvidia tool.
Unfortunately I do not know if this problem is caused by sfml itself. I will also ask in the arch linux forums for this kind of problem. But maybe someone can help :)
