I recently made some changes in my BIOS settings and saw a big jump in FPS! In Hogwarts with DLSS set to 4 Performance, my frame rates went from 120-140 fps up to 180-200 fps at 4k using a 5090. I also noticed an increase in Battlefield 3, going from 180 fps to about 230-250 fps. I’m curious why there’s such a performance difference in CPU-bound games when disabling VT-d and Intel Virtu (VMX). Does virtualization use the GPU and CPU cache in the background that could impact performance?

There’s actually a firmware update called 200s boost that you might want to check out. It can add some performance if you enable it in the BIOS!
Did you have Virtualization-Based Security (VBS) off before adjusting your BIOS settings? If not, disabling virtualization will essentially turn off VBS, which can slow down gaming performance according to some sources. You might want to keep an eye on these settings next time you tweak your BIOS.
Thanks for the info! I hadn’t heard of VBS before, but I’ve had Core Isolation disabled from the beginning. It was the VT settings that really made the difference today!
The FPS boost shouldn’t be happening unless there was some issue with how Windows was working. Intel mentions that their tech plus hyper-threading can affect latency, which could play a role here.
That’s interesting! I tried a bunch of different things back and forth, but the boost was real for me regardless!
Thanks! I already have my D2D set to 3.5GHz, NGU at 3.0, and RAM on XMP II at 8000, but I appreciate the tip!
