[PB 5.42 / 5.50b1] OpenGL vs #PB_Screen_NoSynchronization

#PB_Screen_NoSynchronization is not working with opengl. i only get 60fps, which is my monitors refresh rate:
Code: Select all
CompilerIf Not Subsystem("OpenGL")
Debug "Use OpenGL!"
End
CompilerEndIf
InitSprite()
OpenWindow(0, 0, 0, 800, 600, "Test", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
OpenWindowedScreen(WindowID(0), 0, 0, WindowWidth(0), WindowHeight(0), #False, 0, 0, #PB_Screen_NoSynchronization)
Repeat
Repeat
WinEvent = WindowEvent()
If WinEvent = #PB_Event_CloseWindow
Break 2
EndIf
Until WinEvent = 0
TimeCurrent = ElapsedMilliseconds()
If TimeCurrent - TimeLast < 1000
FPSCurrent + 1
Else
FPSLast = FPSCurrent
FPSCurrent = 0
TimeLast = TimeCurrent
EndIf
ClearScreen(RGB(0, 0, 0))
If StartDrawing(ScreenOutput())
DrawText(10, 10, "FPS: "+Str(FPSLast), RGB(255, 255, 255), RGB(0, 0, 0))
StopDrawing()
EndIf
FlipBuffers()

its probably because i have vsync enabled in the nvidia driver panel. dunno if opengl can override that, like directx can?

In that case it's not a bug.
That settings cannot be overridden. If you want to be able to change it through software, you have to select "let the application decide" or something like that.

there is no such setting. you can only choose between on, off, adaptive and adaptive (half). you can override it with directx, so maybe the same can be done with opengl. im just hoping for some consistency here.
maybe a new mode schould be introduced (#PB_Screen_DefaultSynchronization), which respects the users driver setting and doesnt override anything.

Strange.
Try to Google for "let the 3d application decide" to see what I mean, I wrote some simple OpenGL stuff and this setting was present under different names on both AMD and nVidia drivers for as long as I can remember and across different ranges of cards.
When this is locked, the OpenGL extensions used to enable/disable vsync have no effect.

i remember that setting and when i reset the driver, i can choose that option again. so weird. must have been a glitch in the driver panel. good opportunity to update my outdated driver however.
so yea, this is technically not a bug, but it would be great to have some consistency between the subsystems if possible.
