The 4k display being at 144Hz may not be helping things if the bandwidth is the issue.
The igpu may also be a bit broken as it works fine with passthrough from my dgpu but it was not having a good time running everything off of it with monitors plugged directly into its ports. Browser hw acceleration sometimes caused what seemed like memory artifacts https://u.numerlor.me/PTZj https://u.numerlor.me/PTZj and driver crashes weren't uncommon before I gave up on it. But I don't know if that'd affect performance, and RAM is perfectly stable as that's overclocked and tested rigorously on its own
- vladvasiliu 2y agoThe only machine I've ever had with this GPU setup was a 2013 MBP, which ran perfectly. But yeah, I've heard horror stories with newer multi-gpu laptops, especially on Linux. So, since I've been happy with the 4k performance of iGPUs ever since the hd530 of the 6th gen core, I've specifically looked for iGPU-only laptops.
- Numerlor 2y agoThis was on my desktop with a 7600x and a 7900xtx, I never managed to properly route the dGPU when I have everything plugged into iGPU, seemed like a driver issue where most programs never managed to actually attach to the GPU and got stuck in some driver hell as they were also unkillable. Only managed to get compute and a Furmark vulkan test working otherwise it only works with at least one screen plugged directly into the dGPU
- vladvasiliu 2y agoHuh. I didn't even know this was a thing on desktops. Is this supposed to work with things like thunderbolt displays?
