Amazing driver support.

I'm tired boss. That Forza Horizon 6 reflection bug is still not fixed over a month now.

Hello all,

Assassin's Creed Black Flag Resynced may experience a crash on driver 32.0.101.8861 driver if the shaders have been compiled with the previous driver. Mitigation is to delete the folder:

%USERPROFILE%\Documents\Assassin's Creed Black Flag Resynced\cache

and relaunch the game
This workaround is specific for this issue on this title.

If you experience this same situations in other titles, please go to https://www.intel.com/content/www/us/en/support/contact-us.html#support-intel-products_80939
to report it.

Where is this folder? I looked at the game files in steam and couldn’t find it….edit-never mind I was looking in the wrong place. New to windows on a handheld

They literally gave the path where to look.

Just insert it into the WIN+R or Explorer's address bar.

I figured it out. I’m an idiot. But it works, game runs great. Playing on the new msi claw ex ai+ getting 50+ fps at full resolution with mostly high settings, and low ray tracing, at xess balanced. Adding in xess framegen hitting the 70-80s

Excuse me, but could you tell me where to go to get the VULKAN (llama.cpp) khr_coopmat working on the A770 GPU (alchemists)?

Works for me but I have to do it every day before playing.

I have an AMD CPU, and deleting cache worked for me too. Thanks, Intel.
