Hardware & Technical Preloading shaders taking a while every time after hardware change

Howdy, everyone...

I've run into a minor annoyance, not a showstopper by any means, but annoying nonetheless. Yesterday, I upgraded from an ancient, gas-powered, kick-started AMD FX-8320 to a shiny new Ryzen R5 1600, with the associated motherboard and RAM upgrade. I did a reinstall of Windows 10, keeping my apps and files intact. Everything worked well, and things went mostly without a hitch (aside from being unable to get Windows to activate with the new build, despite making sure I was prepared with a valid digital license.... No worries, Microsoft CS issued me a brand spanking new Windows key...). I did go ahead and reinstall the drivers for my RX-480 card. But now, when I start up ED in my Oculus Rift, the part where it preloads the shaders and the planetary profiles chugs along every time, as if there's been a driver change. It takes a good minute or so every time, with the little white Oculus hourglass popping in and out in the corner. Obviously not a big problem, but with the same card on my old CPU these things took two or three seconds, on a slow day. I reinstalled ED just for good measure, and no joy. I'm wondering if it's something in the Oculus software? Anyone have any such an issue?

Thanks, and Happy New Year!
 
That appears to be an issue with the 17.12 series of graphics drivers, downgrading to the last 17.11 should make the cache work again and most likely won't have much of an impact on anything with an RX-480 anyway.
 
I was observing the same behaviour on my rig. did not change anything but the shaders act as if i changed drivers.
Did not think much of it but cannot test atm.

Thanks. I did consider rolling back my video drivers, but I've been using the new version of Oculus Home, which requires the 17.12 drivers. I guess I'll just have to put up with it for now.

Thanks again!
