Never heard of this CPU. There is no AMD CPU model name that has “x3d” on the end of it.
Regardless, you are wrong. There is no "negative optimization by Blizzard for AMD CPUs. This is a false statement that has been repeatedly parroted by various members of this forum despite no basis or evidence.
Your argument “My friends with intels don’t have problems” is missing a huge amount of context. Like which CPU they’re specifically using, along with GPU. You also didn’t mention your own GPU.
AMD CPUs perform similarly to their Intel counterparts where the specs are similar. There is no reason to make threads like this other than to bash AMD.
I have an AMD Ryzen 9 7900X 12-core 4.70 GHz CPU, which i’ve had for close to 2 years at this point (i.e. its not a brand new model) and I get 300+FPS in normal games, and all but the most intense, unit-spammy custom games it stays well over 60. Whatever problem you’re having is not in any way tied to your CPU carrying the AMD brand name. And whenever a patch is released and people complain about FPS, it affects all users, not just AMD users.
Most of the time, this is just people using a lower end, cheaper CPU and then they compare it to a higher end, more expensive CPU and then say “intel is clearly better.”
You have to compare CPUs of similar price/spec or your comparison is invalid. I can’t make any comparisons for you, because the CPU model as you’ve given in your post does not exist.
