c0burn posted:Thanks for your help. I think I wasn't clear though. Does the performance improvement apply to my CPU? The registry edit floating around on the Forums and the greater Internet applies to anything recent. While Skylake and up on the Intel side can't use retpoline, they still benefit from import optimization, covered by the same edit.

MagusDraco posted:They were specifically asking about their AMD cpu though, a Ryzen 1300x I believe, and if retpoline would help with performance on it. AMD CPUs are also affected by the specter and meltdown mitigation stuff? By recent, I mean like Sandy Bridge or Construction cores. Anything that actually got patched up for Meltdown or Spectre. Yes. The 1300X qualifies.
