Is it just me, or are the latest versions of Unreal Engine, such as 5.3 and 5.4, too buggy for development? My editors and shaders keep crashing constantly, and I’m unable to open my project even if i manage to open it there are endless list of crashes that is crashing the engine at runtime. All related to the Engine code itself! This issue seems especially prevalent with complex shaders, like those from Paragon characters or any other complex custom shaders that involve material parameter collections. Has anyone else experienced this? I have never experienced this buggy Unreal Engine versions before.
hi @JokerDoky ,
The main reason for shader crashes is usually low/old revision of Nvidia graphics drivers for DX12 using Windows 11. Some older graphics cards cannot fully support DX12 under Windows 11
Windows 10 has very stable drivers and virtually no crashes.
Most Epic documentation says “Windows 10 22h2 only”.
Polite way of saying that Windows 11 Direct X 12 Ultimate has Shader problems.
Thank you for the answer. I have the latest drivers and an RTX 3070 Ti. Is this issue only affecting Windows 11 with DX12, or does it also apply to both DX11 and DX12? Additionally, will it be alright on Windows 10 with both DX11 and DX12? I really appreciate you clarifying this—I wasn’t aware of the Windows differences at all.
To avoid any legal problems the wording is “Epic recommends Windows 10 for development” and “Windows 10 22h2 ONLY is supported”
Any PC can be set as Multi version Dual Boot using the Windows 10 installation USB created in by Media Manager App after buying a Windows 10 licence code.
Sometime in the future, this message may change . Epic Fortnite support has been more vocal about this and this message may change.
Basically, UE4 will NOT work properly on Windows 11, because Win11 did not exist!
Essentially Epic ask that developers make sure everything works on 4.27 and the latest 5.4
This means you need to use Windows 10 to test 4.27 apps as for many users this is the latest version they work with.
In the future Windows 11 Direct X 12 Ultimate drivers may be more tuned and tightly written and therefore will be as efficient as Windows 10 DX12 drivers.
