Terrible IT/s on GPUs in last Epoch

[emike09]

Starting with Epoch 104, GPUs are getting terrible IT/s. This has been testing in both WSL and Ubuntu 22.02 native, on different systems. On my RTX 4090, VRAM usage is maximum, reporting 24,491MB used. This seems to be happening to many miners in the discord miners channel. It appears to happen to 4090s, 3080 tis, 3060ti, and possibly more. Tried on client 1.8.10 and 1.9 beta. This appears to be a per-system issue doesn't apply to all systems. One system will function just fine, while another won't. Both affected and non-affected PCs don't respond to reboots in changing whether they are mining properly or not.

Eventually it will get up to something around:

Same to Ryzen 9 7950X3D 59-80 it/s CPU usage 41%. Reboot miner fix issue to 130 it/s in Epoch 104 (100% cpu usage).
After 10-15 min when "Try" change - same problem
Both my rig that same issue

I'm pretty sure the devs don't check the issues page here. Or at least they don't respond.

still having the same issue with my 4090 in WSL and hiveos. Tried different versions of drivers and still no luck.

I just switched GPU mining over to https://www.apool.io/ since it's a PPLNS pool. Wasn't getting any SOLs on 4090 or 3080s trying to find an entire SOL. Their miner seems to run just fine.
