SU Make 2017 not using Hardware Acceleration

Have you run memtest? What are you using for storage? Overclocked?

I have the same GPU and CPU as you in one of my machines (but I have only 16GB RAM compared to your 32) and I have no issues so it’s probably not a hardware issue, especially since you are running fine with other apps.

Yes memtest was run when I built the PC 2 years ago and a couple of weeks ago, no errors after atleast 2 passes. The OS is on a Samsung 970 EVO, the file is saved on a Samsung 860 EVO, but I have tested it on both drives.
Both CPU and GPU were overclocked, but I since testing I have reverted back to stock settings.

After work tomorrow I will try and boot from another drive and see if the problem persists.

Did the drives get set up with an MBR or a GPT partition table? Is the RAM a matched set?
