First off, sorry if this is the wrong section for this question I’m new here and this seemed like the closest match. As the title says I experienced constant issues when using direct12 on unreal 5.3, it would run fine for maybe a minute at most, then would start lagging, then would freeze, then finally actually crash the PC. However, running vulkan it runs just fine, I mean it even runs faster than unity in some cases… Now I have zero interest in actually getting directx to work unless i actually HAVE to. I have no problems with it in any other programs and I don’t want to roll back my driver’s or anything like that. So,
TLDR - IS there any reason I shouldn’t use vulkan when developing on Unreal? Thanks guys!
Welcome to the Unreal Engine Community Forum. This is just my personal opinion. But, in regards to the details of design with Vulkan vs DirectX 12, you’d have to dig pretty deep to find a full list of specifics. But, in general a lot of people use Vulkan. Vulkan has better performance in terms of frames per second and such in many cases. However, many people find that DirectX 12 may have slightly better graphics when you’re getting into the small details. They’re both solid options. A lot of is really just personal preference. I hope that at least shines some light on the subject. I’d recommend doing some Google searches on other designers opinions who have worked with both. It’ll help iron out the opinion.
