Vulkan vs Dx11
Hi there! Just seeing if other people have the same issue that I have. My i7 Geforce gtx 1650 laptop does play the game, but it feels a bit slow whenin dx11, a bit like theres a delay, or if my chars are moving through denser air. If I switch to Vulkan the performance is way better and way more snappy. Only thing is that it crashes every time I get into a dialog. So I am wondering if others do have the same problem, or have some insights. TYVM!

That should do the trick. Chances are it is switching over, but it doesn’t hurt to double check. Laptops are oddballs for the external graphics cards compared to desktops because they share the ports instead of desktops that have dedicated ports.
Have you updated GPU drivers?
I think I did when I installed the game. Will check, though
Vulcan should provide better performance, at least on paper.
That being said, I’ve seen multiple reports of people finding Vulcan crashing. Thankfully you can use comparability mode (DX11).
I don’t think anyone has figured out why yet. Doesn’t seem like it’s a large widespread thing. But there’s not enough information to see the common denominator. The devs would need probably a dxdiag report and a copy of the games config to see what people are doing.

I’ve submitted every crash with crash report, hopefully they will find use for it.
But it turned out that somehow win 10 want using my Nvidia card, but the standard Intel one instead. After switching over my issues stopped and things look smooth and fluid.
Edit: you can check which gpu your game is using under graphics settings, one of the first options is Display Adapter
Yeah I managed to set my nvidia card as a default for everyything through regedit. Silly win10 that it defaulted me to the ‘intel display adapter’ when it has a 1650 to put to use. It works fine now.
Cheers for your reaction, though!
Maybe, it shouldn’t when it’s connected to the mains.
It’s bizarre that it isn’t clear which card it uses, and that changing the default is through regedit instead of display settings…
Vulkan with a mod that replaces Nvidia DLSS with AMD FSR 2.2 it is for me. (this mod only works in Vulkan)
Going to reassess when the update that adds FSR 2 which should work for both Vulkan and DX11. I am playing on Linux desktop and SteamDeck (linux also) so I hope they fix the issues with Vulkan since DX11 goes through a translation layer (called DXVK) on Linux. Theoretically Vulkan should have a lesser strain on the CPU, and it doesn’t need to go trough the translation layer. But currently vulkan on BG3 seams to run a bit slower, cancelling out the theoretical improvements, at least on linux, and also has more crashes. For me it seldomly crashes when loading a game.
For me I am CPU limited and VRAM limited on the Steam Deck, I put a framecap of 30fps, and it does run without that at about 40 to 50fps in the beginning of the game, but I want steady fps so I am using the 30fps cap. I would prefer if vulkan got a little bit better, if it exceeded dx11 a bit, there would be more headroom with the fps, and my battery life would be a bit better.
Not looking forward to the performance of Act3, I might just stream the game from my desktop at that point.
