AMD iGPUs To Get Promising Performance Boost on Linux via PerfOpt Patch
The Linux kernel 7.4 is still a way out, with a late October/early November release anticipated, but it's already showing promising and usability updates for Linux PCs all around, with proper HDMI support with VRR and FreeSync support being just one example. A new patch called PerfOpt (Performance Optimization) is now slated to be merged into kernel 7.4, promising even more performance upgrades for AMD iGPUs.
Per the recent Linux kernel mailing list, PerfOpt "allows privileged integrated I/O devices (GPUs) to bypass the IOMMU when directly accessing system memory. The IOMMU only enforces the IR/IW permission bits without GPA->SPA translations." Effectively, the patch reduces the amount of system overhead for the iGPU, which should result in a performance boost for basically any application that's sensitive to latency or throughput.

GamingOnLinux ☛ NVIDIA security bulletin for Sept 30 notes many GPU issues | GamingOnLinux
NVIDIA released a fresh security bulletin for September 30th that notes quite a lot of issues that have been found in their graphics drivers. You're really going to want to ensure you're up to date this time, I was pretty shocked to see the list enter the GamingOnLinux inbox today.
This is the most I've ever seen in one go. Possibly as a result of more AI being used to track down issues. Like we've also seen for the Linux kernel which has caused Canonical to speed up Ubuntu kernel updates.
