I can’t speak for OP but to answer your questions since I have the problem, I do not have a video capture card, no 2nd gpu, no recording programs (I’ve even removed GeForce Experience). My monitor is an Asus 1080p 144khz freesync, but I’m running it at 60khz since I get no benefit at higher refresh rates given my FPS never goes above 60ish, 40-50 in busier areas. I do have it plugged in in a way that I could see causing problems however:
- It’s my second monitor in a 2 monitor setup (only this one is used for flight sim, mind you)
- It’s plugged in to the secondary port of my GPU which is a GeForce 1080
a. The 1080 has 5 ports: 1 HDMI, 1 DVI, 3 DisplayPort.
b. My main monitor is HDMI only, and plugged into the only HDMI port.
c. My second monitor (the flight sim monitor) has only 1 HDMI in and 1 VGA in. In order to run that monitor from my GPU, I’m using a DVI to HDMI cable.
I’m going to test the sim running on my primary monitor which is HDMI only. I’ll also try making the sim monitor my main monitor and run it directly HDMI<>HDMI.
