No i havent, ill have to try that. When I installed the new driver i had hdr on, when the driver finished installing HDR was not on, but said it was on, and when i turned it to off, it was on. I reinstalled the same driver with HDR off, and same thing happened after install.
Did'nt work, even tried clean install then the new pro drivers.
When i did a clean install and booted into safe mode HDR was on, even though that shouldn't be possible in safe mode. The driver told windows HDR was off when it was on, now, windows is stuck that way i believe.
