FPS Camera rotation is jerky in some configuration
Opened this issue · 7 comments
In OpenGL, both Debug and Release, the camera is very jerky: if you slowly move the mouse camera rotates after a considerable amount of movement.
For Direct3D, there is something different: the Debug configuration is ok, but the release is a bit jerky, but not as the same grade as OpenGL.
I've also disabled SP_WARN(mouse) to ensure that the issue was not caused by lots of printf calls.
I believe this is due to how vsync behaves in OpenGL on Windows. Can you try disabling vsync and see if that fixes the jerkiness?
Where can toggle the vsync?
EDIT: removed vsync writing m_Window->SetVsync(false); in Test3D::OnInit. still jerks.
Umm umm, don't you have to keep m_Window->SetVsync(false); to disable it?
@Xeryko technically isn't it already disabled since it's set to false?
Needs to be tested with vsync turned off in windowed mode.
You should merge with my rawinput pull request, that fixes this actually.
At least for me it does.
Can someone try this again? it seems okay on my end, although Sparky's vsync setting doesn't seem to switch off for OpenGL.
