This is the open-source project sponsored by Valve and planned for use with the upcoming Steam Frame as well as being relevant to Linux gaming on other 64-bit ARM laptops and other devices.<\/p>\n<p>This month brings a number of fixes to its just-in-time (JIT) code as well as further enhancing the performance of it. There have been more x87 instruction optimizations, fixing cmpxchg8b\/16b that was setting some CPU flags incorrectly, and various other instruction fixes with its JIT.\n<\/p>\n<p>FEX 2605 also fixes a crash with ARM64EC and game controller usage like the Sony DualSense controller that could lead to a crash.\n<\/p>\n<p>FEX developers have also acquired some Qualcomm Snapdragon X2 Elite laptops and have begun testing and bug fixing for those latest ARM64 laptops. They noted in today&#8217;s release announcement:<br \/>\n<\/p>\n<p>&#8220;While they don\u2019t yet support Linux out of the box, Qualcomm is pushing commits each kernel release to move the needle. With 7.1 or 7.2 we might even have a working GPU!&#8221;<br \/>\n<br \/>With testing from the Snapdragon X2 Elite, they have fixed some bugs encountered as well as seeing that RNDRRS is still broken like the X1 Elite and noted other peculiarities.<\/p>\n<p align=\"center\"><img decoding=\"async\" src=\"https:\/\/www.phoronix.net\/image.php?id=2026&#038;image=steam_snap_arm64_1_med\" alt=\"Steam Snap ARM64\"\/><\/p>\n<p>FEX is also how Canonical provides a Steam Snap for Ubuntu ARM64 devices.<\/p>\n<p>More details on today&#8217;s FEX 2605 emulator release for Linux x86_64 binaries on ARM64 Linux via FEX-Emu.com.
