I go through a lot of PC's. I build - sell them locally. My usual go to that's been selling great is a 5600 paired with a 3070.
5 PC’s I’ve made with that combination maxes out Dota2 at 1440p with around 350 FPS and GPU utilization hits 99%.
Enter my great frustration. 7600x - 6950XT - 32GB 6000 Mhz C36 Ram - SN 850X M.2. For 2 days now I’ve been problem solving why in only getting around 200-240 FPS in Dota 2 with a stuttering dip to 175 occasionally. The CPU is hovering around 5% and the GPU from 50%-60%. The weird thing is that in the demo when you can try characters is 500+ frames like you would expect - but when I play a live 10 on 10 it starts at 350 FPS then slowly goes down to 240 and stays there or even dips down to 175 for brief moments. There is no thermal throttling. CPU is around 60 degrees and the GPU is between 60-70C with pretty low fan speeds.
I get an amazing score on Passmark 3d, a couple thousand points ahead of the base 6950xt - card draws the proper 300w maxed out.
DDU drivers and reinstalled fresh.
Reinstall Dota 2.
Flashed the newest bios, updated all drivers (including AMD chipset).
Set minimum GPU clock in the Adrenline tuning to 2400 Mhz. The gpu clock runs at 2400+ mhz consistently but stays 50-60% usages.
- Fresh Windows Install
- Disable all variable rate refreshing
- Overclocked CPU and GPU
- Tried with SAM on and off.
- Open GL mode
- Vulkan mode
- Reseated GPU and all the power cables
- Ran the ram at stock and at 6000 Mhz C36
I'm at a loss at why this combo is performing so poorly in this title. It's my go to game. Is there some magic Radeon trick? It's really frustrating that all my 3070-3080 builds have none of these issues - and the one time I try the supposed 1440P FPS king I get this.
Any help you can provide would be greatly appreciated.
