[BUG] AVX 512 Non Cuda v1.6.640 is the wrong .dll #122

Closed Alphonze17 closed 6 months ago

Alphonze17 commented 10 months ago

The .dll present in this file option is incorrect, causes wrong version error on launch.

snottyone commented 10 months ago

no, it doesn't. correct avx512 dll for FSMP 2.1.3. check your game version.

Alphonze17 commented 10 months ago

I even tried to manually put that dll in, same error. Putting in the avx2 for 1.6.640 works though. Triple checked.

From the next fomod:

NOT SUPPORTED ON INTEL CPU!!! Do NOT come with a bug report concerning AVX512 if this bug doesn't happen with the AVX2 build, except if you come with the solution too.

"Intel does not officially support AVX-512 family of instructions on the Alder Lake microprocessors. Intel has disabled in silicon (fused off) AVX-512 on recent steppings of Alder Lake microprocessors to prevent customers from enabling AVX-512. In older Alder Lake family CPUs with some legacy combinations of BIOS and microcode revisions, it was possible to execute AVX-512 family instructions when disabling all the efficiency cores which do not contain the silicon for AVX-512."

Thanks for this report, though :)

I don't follow?

I have an AMD 7800x3d and never mentioned anything to do with CPU feature compatibility.

My issue was only concerning the particular .dll inside the AVX512 for 1.6.640 - I just used one from a different folder which also matched my current version at the time. I only reported it because the .dll in the folder I specified, was not correct for the version it stated it was for.

Pretty sure this is not an issue in the later versions anyway, as I updated and didn't get the same error this time.

Sorry, most reports about AVX512 are about Intel cpus and I assumed wrongly. Will relook at this.

snottyone commented 7 months ago

can't confirm this. FSMP 2.1.3 AVX 512 and 2.2.1 AVX512 no cuda with 1.6.640 launches without problems on an R9 7950X3D

I have checked the fomod logic, and the visual studio build logic, and haven't found anything. Your processor should be compatible with AVX512, so it isn't this either.

So, it seems you're right :) : "Pretty sure this is not an issue in the later versions anyway, as I updated and didn't get the same error this time."
