force_resolution doesn't fix refresh rate locked to 60 Hz

Open Keith94 opened this issue 4 years ago • 4 comments

As per title, force_resolution is set to 1920x1080x120, but game (Dx11) still runs at 60 Hz.

Your in-game refresh rate may be automatically capped to your monitor's refresh rate by the GPU driver. Also, during loading screens, the refresh rate is capped to 60. Not sure how much I can do about it.

Hi, I should clarify this a bit. If the game is running in DirectX11, it defaults to 60 Hz refresh rate even if Resolution:1920x1080x120 is selected in Documents\Rockstar Games\L.A. Noire\settings.ini and your desktop is running at >60Hz. DirectX 9 version doesn't exhibit this problem.

There is a workaround with the 3Dmigoto wrapper with changing this bit in the .ini:

; overrides refresh rate set by game. ;refresh_rate=60

Maybe it's possible to add this fix if there's enough interest. Useful for any Gsync or high refresh rate owners. :)

For me, running the game in a borderless window (which the patch does by default) makes it run above 60 FPS. I gather that you have an Nvidia GPU, so this might be vendor specific (as I have a Radeon card).

Anyway, definitely will look into that and what can be done about it.

Thanks, and you're right, this issue only affects exclusive fullscreen mode. I wanted to suggest a setting like:

override_refresh_rate=0

0 = use desktop (default) -1 = disable override 60/120/240 = specify custom hertz
