Like the title says, running a display at 2560x1440@144Hz with “force composition pipeline” enabled doesn’t run it at 144Hz. It’s hard to tell what exactly is happening but the display is definitely not running at the full 144Hz. Comparing side by side with a 1920x1080@144Hz display, it looks noticeably worse. Lowering the resolution to 1920x1080@144Hz works as expected so I believe it has something to do with the resolution specifically. On Windows, 2560x1440@144Hz works just fine. I’d like to be able to force the pipeline on for vsync as I find it much more reliable than what compositors do.
Running on RTX 2060 over DisplayPort 1.2 with Linux 5.9.14, driver version 455.45.01.
