Ghost Recon: Wildlands has had a few technical issues on PC, and patch 1.1.5 released today addresses some of those problems, particularly with quad-core support and graphics improvements.

Here are the full patch notes (again for PC only):

• Multi-GPU improved support: We have been working with our partners to improve both SLI and Crossfire support. Various stuttering and graphical corruption issues have now been fixed.
• Quad-core CPUs improved support: Several freezes and performance issues have been resolved for players using quad-core CPUs, notably Intel i5 based setups.
• AMD graphic cards improved performances
• Enhanced mouse navigation in store menu
• 4K menu background scaling implemented 
• Several crash sources have been addressed
• Improved Ansel support and fixed bugs
• Various fixes for the Steam Controller integration
• Other bug fixes & improvements.

The graphics improvements are of particular importance for AMD users, as Nvidia and Ubisoft had worked closely together before launch on several performance enhancements for its higher in GeForce cards, including 4K support and Ansel support. Even with that early support, today's patch addressed bugs and extra Ansel issues.

The patch is now available on Steam and Uplay, and while the update should make PC players happy, the development team is still working on massive laundry list of known issues on all platforms.
