FEX 2511 is out today for this open-source emulator akin to Apple's Rosetta that allows running x86/x86+64 applications on ARM64. But in the case of FEX, for ARM64 Linux devices and akin to other open-source projects like Box64.

The FEX open-source project continues going strong with enabling various Linux x86/x86_64-only games -- including Windows games running under Valve's Steam Play (Proton) to run on 64-bit ARM devices with increasingly good speed and for the most part a very pleasant experience. With FEX 2511, there are yet more performance optimizations in tow.

FEX 2511 has more work on its just-in-time (JIT) handling as an almost monthly theme. There are now potential memory savings with the latest JIT in FEX 2511. Plus the JIT has seen some crash fixes. And then an assortment of other performance improvements.

FEX is also now enabling Advanced Vector Extensions (AVX) emulation for 32-bit software by default. They weren't enabling 32-bit AVX out of fear of stack overflow issues but they believe those edge cases to now be resolved. The one caveat to note still though is that it's not wired up for Wine's WoW64 emulation due to missing features on the Wine/Windows side.
