Baldur's Gate 3 Benchmark Test & Performance Analysis Review
Baldur's Gate 3 is the newest RPG masterpiece by Larian Studios. The graphics are excellent for a top-down isometric RPG and you also get support for DLSS, DLAA and FSR. In our performance review, we're taking a closer look at image quality, VRAM usage, and performance on a selection of modern...www.techpowerup.com
This is only vram usage but looks lke at 1080p it would use roughly 3GB of vram. Giving the series s another 5+ gigs of ram to work with. It would be interesting to see total system ram usage. I also found this interesting from the article
aldur's Gate 3 has support for DirectX 11 and Vulkan—we've tested both. Surprisingly, there's very little difference between both renderers, they look exactly the same, the FPS are very similar, and even the minimum FPS, too. What I noticed is that Vulkan doesn't have much dynamic memory management. While DirectX 11 will always load and unload textures to manage VRAM optimally, Vulkan just seems to load everything that's nearby into VRAM and that's it. This is supported by our VRAM usage numbers, which are roughly 1-1.5 GB higher with Vulkan than on DX11. I also noticed a crash with the 4 GB Radeon RX 6500 XT, which suggests that the Vulkan renderer is not able to overflow VRAM into main memory, whereas the DX11 renderer has that ability. Given these results, my advice is to use DirectX 11, it looks the same, and seems to be more mature than the Vulkan renderer. While there's claims of smoother frametimes I have yet to notice any meaningful difference for that either. Do let us know your experience in the comments. The renderer does make a big difference for Intel Arc GPUs, which run considerably faster with DirectX 11.
So it looks like there could be better performance unlocked if they figured out how to use vulkan better.
