> Edit: Just want to make one point really clear; these errors don't generally manifest out of the box. That is, it takes time before the CPU becomes affected. In my case, every CPU took between 1-3 months before the exact same behaviour started to show. DX12 and shader comp, either at initial shader comp or during gameplay, would crash the game client out.

> The issues started small. Very occasional errors as per the title, when trying to load the game, but clicking away and trying again would mostly work. Then sometimes work. Then never work, indicating the CPU was degrading. Then even in times where it would load to the menu, trying to get to the staging area would crash out, again with the same error. Checking the game log, it pointed to the shader comp causing a fatal error.

> Replacement CPUs fixed all that. For a while. But in those cases, the game would load up and go into a match but during gameplay, would CTD. Checking the game log again, it showed that shader decompression, due to traversal, was again causing a fatal error.

Uh oh, looks like the physical CPU itself degrades over time. The problem here is that currently, the only fix once you start experiencing the degradation appears to be a complete replacement of the CPU. I have a sneaking suspicion we will see some micro-code or dodgy kernel patches which affect performance.

The only current proposed work around will buy time, but will still degrade:

> "Intel i9 13900k/i7 13700k: Underclock 'Performance Core' Speed It has been noted that players with the Intel i9 13900k/i7 13700k CPU are prone to these crashes. Players have been able to work around this by underclocking the 'Performance Core' speed using Intel XTU, from x55 to x53."

Note to self, steer well clear of Intel for a while.
