KNOWN ISSUES

Vulkan support is now live for DOOM on PC. Below are some frequently asked questions, along with links to download the most recent drivers. Please also note that Steam controller support has also been included in this patch, so we've included some FAQs relating to it below as well.Please be sure to update your drivers to these new versions as they are required for Vulkan:NVIDIA: 368.69 - Download the latest NVDIA drivers: http://www.nvidia.com/Download/index.aspx AMD: 16.7.2 - Download the latest AMD drivers:Vulkan is a revolutionary graphics and compute API technology developed by the Khronos Group that allows game developers to interact with graphics hardware at a lower level, allowing for more efficient use of hardware, improving game performance.On DOOM, Vulkan allows PC users to experience significant performance boosts on supported GPUs and CPUs, translating directly to better gameplay feel.Most users on the minimum spec end of hardware will experience better performance at higher video settings. Users whose have recommended or above specs will experience exceptional performance with DOOM’s advanced video settings cranked up to full effect.We’ll continue to work with AMD, NVIDIA and the Khronos Group to unlock the Vulkan API’s full potential through idTech 6, giving DOOM PC players a gameplay experience unlike anything else. Stay tuned for more updates.For additional information on the Vulkan API, please visit the following links.AMD: https://community.amd.com/community/gaming/blog/2016/07/11/radeon-graphics-takes-doom-to-the-next-level-with-vulkan-implementation DOOM Vulkan support will be enabled via a patch that goes live on Steam at 10:00am ET on Monday, July 11th, 2016. Vulkan will not run properly without updating to the latest unified drivers from AMD and NVIDIA for supported GPUs.For more information on drivers, see the article below:When launching DOOM from Steam, you’ll be prompted with a new menu to choose either OpenGL or Vulkan. To play with Vulkan, select the second menu option. You can also switch between OpenGL and Vulkan in game via the Advanced Settings options menu. The game will restart whenever you switch between OpenGL and Vulkan.If your graphics card meets the DOOM minimum requirements, it likely supports* Vulkan, but you’ll need the correct version of your GPU drivers in order to take advantage.*Vulkan is not currently supported on NVIDIA GPUs with 2 GB of RAM on Windows 7 or on the GTX 690. Users with these GPUs need to run DOOM on the OpenGL graphics API.For more information on drivers, see the article below:The minimum PC specs for DOOM remain the same.To enable uncapped framerate, v-sync needs to be disabled via the in-game options.Asynchronous compute is a feature that provides additional performance gains on top of the baseline id Tech 6 Vulkan feature set.Currently asynchronous compute is only supported on AMD GPUs and requires DOOM Vulkan supported drivers to run. We are working with NVIDIA to enable asynchronous compute in Vulkan on NVIDIA GPUs. We hope to have an update soon.Click here for additional information on asynchronous compute.Once DOOM is loaded, the title will automatically detect the presence of the Steam controller and adapt controls and button prompts to match. No additional configuration is needed to use the default controller profile.The NVIDIA GTX 690 is not currently supported to run Vulkan on DOOM. Users with this GPU will need to run the game on OpenGL .Vulkan is not currently supported on NVIDIA GPUs with 2 GB of RAM on Windows 7. Users with these GPUs need to run DOOM on the OpenGL graphics APIf this issue occurs, exiting Object mode back to Blueprint mode, before going back into Object Mode may correct the issue. If the problem persists, we recommend you run the SnapMap editor on OpenGL (you’ll still be able to play your maps on Vulkan).This is a known issue with Vulkan API and AMD GPUs.This is a known issue while running DOOM on the Vulkan API.Graphical corruption may occur after resizing the game window while in windowed mode, and then switching the display mode from windowed to full screen. If this occurs, restarting the game application should correct the issue.It may take longer for some users to launch SnapMap on Vulkan than it does on OpenGL.We are currently investigating a fix for this to include in an upcoming patch.While we are working on a fix for this with AMD, affected users should run the game with v-sync disabled.This is a known issue with the Steam Controller. An alternate control method can be used to rotate the map in the automap interface.
