Deus Ex: Mankind Divided hasn't had the best launch on PC. Gamers have discovered a range of issues including crashes and horrible mouse acceleration that cannot be disabled in any of the game's menus.
Developer Eidos Montreal is aware of the issues with the PC version, and have already published a patch that addresses numerous crashes with the game. Version 1.0 build 524.7 specifically adds the following fixes:
• Fixed crashes caused by third-party programs interfering with the game.
• Fixed crash that occurred after viewing the intro videos.
• Fixed issue that could cause a crash at the end of the Prague intro scene.
• Fixed mouse invert setting not being displayed correctly in the options menu.
Eidos is also warning people that Mankind Divided is a very demanding game from a performance perspective, and any "optimization" issues may simply be gamers attempting to run the title on quality settings that their systems cannot handle. The developer recommends starting the game on the High quality preset with MSAA disabled and begin increasing settings from there.
We've been performance testing Deus Ex: Mankind Divided on a range of PC hardware over the past few days – you'll soon see the full benchmarks published here on TechSpot – and we've found that the Very High and Ultra presets are particularly demanding. However, the visual quality of the game is astonishing at these presets, so low frame rates don't seem to be an issue with optimization.
There is a DirectX 12 patch coming in the next few weeks, which could potentially improve performance in some situations, but we'll just have to wait and see.
The problem with mouse acceleration seems to be the only main issue that has continued to affect users after the release of the latest patch, although some users are still reporting crashes at times. Hopefully Eidos can continue to improve the experience on PC over the next few days, as Steam reviews have already taken a hit from users submitting negative launch day feedback.
