Your out of luck I'm afraid. Most mods dont work on DirectX12, Vulkan is the only way to go and also has better performance. I dont know what you mean by "renders better", they should both have the same visual quality.
LMS it'd be great if you could read dominatorgt's comments on Nexusmods, he seems to have found something that could aleviate the texture streaming issue that causes assets to not load in the game due to the engine being at its limit. I believe this also has to do with the unbereable stuttering lml causes because of the constant drive readings. He there explains why his method is easier on the drive (but uses more VRAM) and seems very knowledgeable on programming, hopefully you guys can talk and share this with the rest of creatos. Thank you very much.
PLEASE fix the stuttering because for some reason after I install this the game starts having frametime spikes which causes the game to lag like crazy, I THINK due to spikes in drive usage even when using an SSD. It not only happens to me but also a lot of people I know and with high end computers, the stutter is unbearable and it's the only way to add good mods to the game. This happens only after putting the lml mod to the root folder of the game, vanilla game works just fine. I can test and send you more details if you want. The first photo are the frametimes running the game with lml installed and NO mods, the second one is the vanilla game with scriphook and rampage installed.
