The repository will automatically used for new CachyOs installations on AMD Zen4 and Zen 5 machines to provide best performance.

A new CachyOS snapshot for July 2024 is out today with lot of improvements and new features especially for AMD users and usual bug fixes and other changes to improve your experience.

CachyOS hardware detection tool get help for configuring the libva driver as default for supported NVIDIA hardware along with ability to correctly export the variable to profile.

AMD uses get help for AMD CPB Boost feature which permit enabling or disabling the boost on per core basis which is supported in CachyOS kernel by default.

Beginning with this release CachyOS will enable a software repository on new installation that will be used to provide performance for AMD Zen 4 and Zen 5 machines.

ISO now features automatic architecture checks for Zen4/Zen 5 repository ans Cachy OS hardware detection tool get help for AMD GPU for detection of official Room supported GPUs.

CachyOS graphical installer Calamares has been update to use only Tier 1 Mirrors from Arch Linux install the latest archlinux keyring package from Arch Linux before starting installation to avoid issues and remove unused CachyOS repositories from config and copytoram kernel parameter was changed from yes to auto to avoid issues on machines with less RAM.

CachyOS Kernel Manager tool now has GUI to control the sched ext scheduler allowing users to enable or disable the scx service switch between different sched ext schedulers and set command line flags for them.

The July 2024 release of CachyOS removes unmaintained Cutefish software and userspace Kernel sampage merging daemon.

Upscaling technologies continue to improve every year and with AMD latest updated FSR 3.1 tech finally into few games.

We will be discussing at 5 games that have been updated to use FSR 3.1 along with lates and greates upscalers from Nvidia and Intel in form of XeSS 1.3 and DLSS 3.7.

AMD decoupled frame generation from FSR permitting users to now utilize AMD frame generation tech with Xess or DLSS or even native resolution.

They are building FSR into a DLL file that ships with games.

When AMD revealed FSR 31 they promised various improvements to up scaling component like temporal stability for decreased shimmering and flickering enhanced ghosting reduction and better preservation.

FSR 2.2 and release of FSR 3 AMD upscaler was worst of temporal stability.

Which upscaler should AMD GPU owners use: XeSS 1.3 or FSR 3.1?

XeSS typically performs worse than FSR on AMD GPUs at same quality preset and worse than Xess on Nvidia GPUS which means you have to use low quality modes to get similar level of performance as FSR.

In games like Horizon Forbidden West it difficult using XeSS when quality at performance normalized setting is notably worse.

Xess vs FSR vs DLSS where do they stand using latest versions?

DLSS is better with version 3.7 continuing to improve upon technology. Earlier version of DLSS there are few facts now and Nvidia continues to evolve the tech as their contest tried to catch up.

GeForce owners are getting more better upscaling solution that produces the best image quality.

There are reasons than ever for game developers to integrate all three technologies. DLSS is king for GeForce owners and offers best overall quality XeSS provides decent upscaling quality for those who do not have GeForceRTX GPU and FSR3 without GeForce 40 series GPU.

Upscaling ecosystem has kept improving and FSR 3,1 is step in right direcion. AMD should absolutely not take this as last victory.

FSR 3.1 vs FSR 2.2

The first thing to reach is whether FSR 3.1 is actually an improvement over FSR 2.2.

Ratchet is not good example of FSR 2.2 as it has mega issues so it present mega chance to see where AMD has improved.

AMD FSR 3.1 changes

  • FSR 3.1 upscaler reduces ghosting improves convergence speed and decrease flickering
  • Frame pacing for FSR Frame Interpolation has been improved for better experience
  • FSR 3.1 updates the ability to decoupling the frame interpolation process from that of upscaling
