Or should we proceed from now on using just the current release (I assume it's v29.8)? I just observed that prime95 now includes options to disable AVX, AVX2, and even AVX-512 for processors supporting those instructions. Would executing the updated prime95 version with smaller FFTs or combining it with AVX instructions be technically the same as running the identical tests in 26.6? Or were other adjustments made to those tests compared to the previous versions? The descriptions in the app for the small FFT test differ between versions:

v26.6: Small FFTs (max FPU load, data fits in L2 cache, limited RAM testing)
v29.8: Small FFTs (test L1/L2/L3 caches, max power/heat/CPU stress)
Also, the new version introduces another "smallest" FFTs test:
v29.8: Smallest FFTs (test L1/L2 caches, high power/heat/CPU stress)

How does this compare to the small FFTs tests in 26.6 and 29.9?

Thank you!!!

Up to the newest release, adjust AVX settings as needed.
