A New Kernel Patch Is Being Discussed That's Needed For Newer Windows Games On Wine

Newer Windows games/applications are making use of system call instructions from the application code without resorting to the WinAPI and that is breaking Wine emulation support. A Linux kernel patch is now being worked on for addressing this issue in the form of system call isolation based on memory areas while having a smaller performance hit than alternatives.

The Ongoing CPU Security Mitigation Impact On The Core i9 10900K Comet Lake

At least for the workloads tested this round, when booting the new Intel Core i9 10900K "Comet Lake" processor with the software-controlled CPU security mitigations disabled, the overall performance was elevated by about 6% depending upon the workload. Here is a look at the out-of-the-box security mitigations for this new Intel desktop CPU against foregoing the default CPU security mitigations and running an unprotected configuration to see what the pre-Spectre performance looks like.

Steam Ironing Out Shader Pre-Caching For Helping Game Load Times, Stuttering

Valve developers have been working on Vulkan shader pre-caching with their latest Steam client betas to help in allowing Vulkan/SPIR-V shaders to compile ahead of time, letting them be pre-cached on disk to allow for quicker game load times and any stuttering for games that otherwise would be compiling the shaders on-demand during gameplay, especially under Steam Play.

Ryzen 9 3900X/3950X vs. Core i9 10900K In 380+ Benchmarks

Following our initial Core i5 10600K and Core i9 10900K Linux benchmarks last week, here is a much larger comparison I have been working on since then in looking specifically at the Ryzen 9 3900X and 3950X against the Core i9 10900K. It's the largest to date with nearly 400 benchmarks being tested, most of them real-world test cases.
