Stuttering with mobile 4090, but NOT with integrated graphics
Posted: 20 Jun 2023, 21:38
Hi! First off, very helpful site and tools. They've been very useful in demonstrating the stutter problem that I've been experiencing with my new laptop. So, my problem is this - at my 240 hz refresh rate, my laptop's 4090 has noticeable slowdown/speedup/hitching/micro-stuttering, even when I'm hitting 240 fps at low settings. The card is performing well as far as fps and settings are concerned, and the temps are fine, but the frame timings are just very bad. The movement across the screen just feels inconsistent. When I disable my 4090 and use the intel igpu, the problem disappears entirely. I'm using the latest nvidia drivers, and I've tried disabling/enabling gsync and vsync in the nvidia control panel. Any ideas about what can be causing this behavior?
The first picture is with only my graphics card enabled (optimus off, gpu only). The second picture is with my graphics card off (igpu only).
