Screen tearing in fullscreen mode on Windows 10 with NVIDIA #138

mariomadproductions commented 1 year ago

I get screen tearing in fullscreen mode, with both GlideN64 and Parallel. Turning on vsync fixes it, but it adds input lag, and I assume its unusual for there to be tearing by default anyway. The input lag is higher in windowed mode than fullscreen mode, so I can't really just use windowed mode (plus the borders are annoying).

For some reason the tearing also stops if I'm recording with OBS using a Display or Game Capture input type.

I don't have an issue like this with PC games, and I tried BizHawk (as its another mupen64 frontend/near-upstream fork, afaik) and don't have the issue there (although that has very bad input lag). Also tried RetroArch, no tearing with vsync on or off.

RMG version: v0.4.1
OS: Microsoft Windows 10 Enterprise LTSC (v10.0.19044)
GPU: NVIDIA Geforce GTX 1650 (driver: v31.0.15.3179)

I asked someone else to help me test this, and he managed to reproduce the issue with this configuration (although he didn't try the OBS thing):

OS: Microsoft Windows 10 Pro (v10.0.19044)
GPU: NVIDIA Geforce GTX 2080 Ti (driver: v31.0.15.3179)

This is using default RMG settings (except configuring controls), and for me, default GPU settings.

Please tell me if there's any further testing that could be useful/any further details I can provide. Thanks.

Seems like retroarch has the same amount of lag (give or take retroarch being one or two frames faster) with vsync on, so I guess this is probably a GlideN64/Parallel issue.
