Well there's a thing.
Tried the GTX 1050Ti in my other PCIe slot (which is really tight!) ... and it worked!
So tried the 1050Ti in the slot I usually use ... and it worked! (It gave me a moment's hesitation where Oculus reported instead that it wasn't even compatible - but's that because I had jumped the gun and tried it before Windows had recognised the card fully.)
So it's the GPU that the Rift S doesn't like. Or at least the GPU when combined with my other hardware. Weird.
I guess I'll report this back to Oculus and see what they suggest. But I can't see what they can suggest apart from changing my GPU.
What's a worthwhile but cost-effective upgrade from a 1080Ti? I probably will want to stick with nVidia as I have a GSync monitor.
Definitely the same? Because they have quite a range of 1080Tis for some reason. From this page:I have the same video card as you.
How odd.
Interesting. I was wondering about the 2070S myself - given I can sell my 1080Ti it should be too huge a cost to change. When you say it makes more of a difference for VR, why is that?
You had me proper excited then - because it did need an update.
But still didn't work when it was completed.
You reinstalled the latest graphic drivers are doing the firmware update?
Wait a sec - I didn't do this. You're saying to re-install nVidia drivers after the firmware update? Even though they're already the latest drivers?
I'm pretty convinced on the 2070S. The difference in the benchmark scores from that to the various 2080 offerings just don't seem to justify the extra outlay.
Re-installed, didn't work.
I do have nVidia support now looking into it (pleasantly surprised that they didn't wash their hands of it in the same way as Oculus support now have), but I'm pretty resigned to replacing my GPU.
Your continued help over 7 pages has been immensely appreciated!
