Continuing the discussion from Performance tanked after installing (?) 4090!:
After trying the suggestions made in response to my post above did not solve the problem, I returned the 4090 and requested a replacement. The replacement came yesterday and after a couple of failed boots, in seemed to have installed OK. As usual, I first ran Time Spy and the results were everything I’d hoped for my: system went from 18349 to 25416.
User Benchmarks were also good:
UserBenchmarks: Game 351%, Desk 109%, Work 330%
CPU: AMD Ryzen 7 5800X3D - 107.4%
GPU: Nvidia RTX 4090 - 340.9%
SSD: WD Black SN750 NVMe PCIe M.2 1TB (2019) - 247.6%
SSD: Adata SU760 512GB - 101.8%
RAM: G.SKILL F4 DDR4 3600 C16 4x8GB - 129.3%
MBD: Gigabyte GA-B550 AORUS ELITE
Second 4090
I first tried a 2d MSFS flight using GeForce “Optima;” setting and it was superb. But when I tried VR, it was as described in my previous post: so slow you couldn’t possible fly. I tried again after removing the optimal settings (thinking they probably only applied to 2d and got the same poor performance.
This morning I resumed my attempts to find out what’s going on and I ran Time Spy again: the result: 1203!! Approximately 5% of my previous score! The Kombuster score also tanked to 968 and 15 FPS.
I cannot fathom this. How can changing the GPU causes such radical changes in my system? Even further, how would I go about trouble shooting this? I am at a complete loss and would (as you could imagine) be extremely grateful for and assistance.
I just checked HLA and, as expected, it’s performance is severely degraded also. It’s a though a single run of a VR program causes some permanent degradation in my system.
