Msi afterburner settings11/24/2023 Meanwhile, Intel GPUs show a performance advantage for Vulkan in CPU-limited scenarios. Areas with NPCs run quite similarly on either API in Nvidia and AMD GPUs, with only around a four percent difference in favour of DX11. It should be noted though that our AMD GPU with DX11 and Vulkan produced more variable frame-times than our Nvidia and Intel GPUs in both APIs, with larger spikes recorded with the AMD GPU - up to 270ms in Vulkan (vs 27ms for Nvidia and 23ms for Intel) and up to 107ms in DX11 (vs 20ms for Nvidia and 42ms for Intel). In such scenes both graphics APIs show a similar level of frame-time stability, with small hitches occurring at similar moments as the area is traversed around NPCs. In contrast, Intel GPUs show Vulkan being 13 percent faster in this scenario. When CPU-limited in these NPC-driven moments using Nvidia and AMD GPUs, Vulkan and DX11 perform more similarly - with DX11 actually taking the lead in average frame-rate by around four percent. In combat scenarios or in a populated town area, NPC calculations become the most expensive CPU process. However, this advantage is only maintained in scenes with few characters. In a static scene devoid of NPCs, both AMD and Nvidia GPUs ran ~21 percent faster in Vulkan than in DX11, while Intel GPUs ran 29 percent faster in Vulkan. However, things change if you are CPU-limited (ie your GPU is showing less than ~99 percent utilisation), which is most common at 1080p or lower resolutions and/or with older CPUs. *Note: You can check GPU limitation using the Performance tool in the Windows Game Bar overlay (Win + G), by using tools like MSI Afterburner + RTSS, or by leaving Task Manager's Performance > GPU window open on a second screen. Vulkan provides better performance in CPU-limited scenarios - at least with few NPCs around. When GPU-limited, DX11 offers a measurable performance advantage over Vulkan on Nvidia and Intel GPUs. With an Intel GPU, DirectX 11 runs around 25 percent faster than Vulkan.With an AMD GPU, DirectX 11 and Vulkan run nearly identically. With an Nvidia GPU, DirectX 11 runs around eight percent faster than Vulkan.This is a likely scenario for running at 1440p or higher resolutions, with higher graphical settings, on a PC that meets or exceeds the game's recommended specifications (RTX 2060 Super/RX 5700 XT, paired with a Ryzen 5 3600/Core i7 8700K). Let's start with the most common example - being GPU-limited (ie your graphics card showing ~99 percent utilisation*). We trialled both options on a range of systems with Nvidia, Intel and AMD graphics card to tease out any differences and come up with some recommendations.įollowing our testing, we do have some answers - but things aren't as straightforward as we'd hoped, with different system configurations producing different recommendations. The Baldur's Gate 3 launcher offers a choice between DirectX 11 and Vulkan - so which is the best in terms of performance and stability? The launcher defaults to DX11, while Larian support documents suggest Vulkan, so in the face of this conflicting advice there's only one thing to do: get testing.
