We are going to focus on the 1080p gaming performance, to look at any differences in CPU performance while gaming. We are using an NVIDIA GeForce RTX 4090 Founders Edition video card with driver version 560.70. All games are being run in their “Ultra” game settings, at native resolution, and with no ray tracing. The results with the Microcode Fix 0x129 BIOS applied are highlighted in blue, while the grey bars are using the BIOS previous to this new one, without the Microcode fix. We will test both the Extreme and Performance Profiles.
