Lords of the Fallen got plenty of patches in the last few days, with two of them, Patch 1.1.199 and 1.1.203, launched yesterday, and the latest, Patch v1.1.207, launched earlier today. The previous two fixed GPU crashes on AMD graphics cards, as well as a big fix for the issue in communication between the drivers and DirectX 12. The Patch 1.1.203 also brought a reduction in VRAM usage that should provide additional headroom for GPUs operating at the limit, which in turn should provide a substantial performance improvement, at least according to Paradox Interactive.
The latest Patch 1.1.207 brought further stability improvements, fixing several crash issues as well as implementing various optimization, multiplayer, gameplay, AI, Quest and other improvements. The release notes also note that the fix for the issue that causes the game to crash on Steam Deck has been fixed, and should be published as soon as it passes QA.
