Going through the wiki page, I've noticed a few things that need some tweaks. Here's what I found:
-In the Mercenaries United section, "(which means score is more important than time)" is confusing, it should say "which means combos are more important than time".
-In Field of view it says textures become buggy, but it's more about the actual 3D models disappearing.
-As for shadows, while the medium and high values are correct, low simply disables dynamic shadows altogether, and certain cutscenes force shadow rendering which I believe uses the medium resolution (could be high too, can't remember which).
-PC exclusive slavic languages (if we ignore the Nvidia Shield TV version which has the same issue, PC port) such as Czech, Russian and Polish weren't updated to support DLC content, among other smaller related issues.
-If I'm not mistaken, a retail version of the game would refer to an original GFWL game disc from the 2009 release, meaning the QOL patch does not actually work with retail versions of the game. Also, the patch is still functional as it automatically downgrades the game version, but it does have other issues in its current state, as capcom decided to create separate leaderboard and session list servers for the 1.2.0 patch.
