Fps drop to half when change to lower resolution
« on: December 15, 2020, 04:57:52 am »
Hello
I have some strange behavior.
My sfml app run fine with 60fps (vsync on) in 1280x1024 desktop.
(I'm still using a 4:3 screen monitor)
Then I want to test something so I try to change the desktop resolution to 1280x720
which is lower than the previous resolution.
But the result is my app run very lag and fps drop to 30.

PS. I also try to set Vsync on-off but my app still looks very lag even it got 700fps.

Does anyone have an idea what happens?
Thanks a lot in advance.

does this happens only in SFML? whats about other applications, made with and without OpenGL?
1280x720 may be not optimized for your hardware, did you try 1024x768?
