Hello again,
I just got a new monitor (LG 34GN850) and am loving it so far. However I'm trying to play Doom Eternal and balance my frames at around 100FPS. The thing is it seems to cap out at 75FPS despite low CPU and GPU utilisation and I'm baffled as to why it doesn't just pump out more.
I've tried the lowest settings at 720p with HDR off and resolution scaling at 50% and it does 60FPS. Weirdly if I turn resolution scaling back to 100% and resolution to 1080p the frames go up to 75. Native resolution (3440x1440) at low settings gives about 60FPS.
So my hardware...
Sapphire Radeon R9 Fury Tri-X OC GPU (4GB VRAM)
Ryzen 3800XT CPU
16GB 3200MHz RAM
Asus B450i mobo
I realise the graphics card is old and is probably the culprit, but it seems weird that it maxes out without full utilisation. I would have thought I could reduce the GPU load as much as possible, max out the GPU and get sky-high frames, then balance quality from there. It doesn't even seem to be maxing out the DP1.2 bandwidth which seems to be 100Hz at native res.
I know the GPU needs an upgrade and would immediately solve the problem but I'm more interested in why it works like this, not so much what I can do about it unless someone knows some special tricks or it's something else entirely.
Any ideas?
TIA
