http://bugs.winehq.org/show_bug.cgi?id=60405 --- Comment #1 from thomasabbott916@hotmail.com --- I want to add for some context: 1. This was found by debugging why the perf of non-ARM proton was outperforming ARM64 proton for Final Fantasy XIII. It was found that this issue is not present in the x86_64 stack, only on the ARM64 stack... With the fix fps goes from 48 -> 66 fps (37.5% increase). 2. SSBS is just one of many flags being cleared. Some small exploration showed other flags (like DIT) might also need to be preserved ideally. I think a fix for this should explore it through a general lens. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
