Been fine tuning a couple of things this morning. After updating the nvidia drivers yesterday for the first time in ages I did clean install, but didn't amend any settings in the control panel. With everything now set to PHENOMENAL COSMIC POWER, and updating precision x which had thrown a wobbly or 5, was getting much more consistent results: 2484, 2479 and 2485. With that and a couple more benchmarks for comparison, I swapped out the cheapo power pci riser i bought off ebay for the posh new Corsair model. Before: After: Much better! And the result, straight off the bat, a new high score EDIT: Top score now 2503! Max temps 51C on GPU, 53C on CPU. Noice. Also pushed my top Heaven score from 1482 to 1500 (max settings at 1900x1200), and Far Cry 5 bench from 3877 frames to 4040 frames (on Ultra, 1900x1200).
I thought I'd posted the Superposition score from my new desktop, but apparently not. Here it is - that's based on the daily settings, I haven't done anything to make it quicker-like.
