Our notes on Vulkan Optimized
What sets it apart
Vulkan Optimized is built around VulkanMod, a mod that replaces Minecraft’s OpenGL renderer with a Vulkan one. The author says this is a full renderer replacement, not an add-on to Sodium, and that the rest of the pack was chosen to avoid clashes with it. Sodium, OptiFine and Canvas are left out for that reason.
The latest build lists 25 projects. Around VulkanMod sit Lithium, FerriteCore, Krypton, ScalableLux, Entity Culling, More Culling, ModernFix, BadOptimizations, AsyncParticles, Dynamic FPS and Ok Zoomer.
Who it suits
Players curious about Vulkan rendering who accept the trade-offs. It is a client-side tool aimed at frame rate and efficiency, not visuals.
Before you install
The author lists several limits. Shader packs do not work, since VulkanMod’s shader support is described as improving but not comparable to OptiFine. On Linux it runs under Xwayland, with X11 also expected to work. Windows 10 and 11 will probably work but are not confirmed by the author. Results on NVIDIA cards may vary, and the author says AMD hardware is where it performs best. There is no Forge version.
The author’s page includes a table of FPS and power-draw figures from one personal machine, but it publishes no test method (no scene, run count or settings), so those figures are not repeated here. The author also says the pack draws more power because it uses the GPU harder. No RAM measurements are published; the author’s test setup allocated 6 GB to Java.
Listed versions run from 1.19.4 to 26.1.2 on Fabric only, with the project last updated July 16, 2026. The license is all rights reserved.
No wiki or repository is linked on the page.
Playing with friends
Modrinth marks the pack as required on the client and unsupported on the server, and no server files exist. Because only the client renderer changes, friends do not need the same pack. The page tags it Multiplayer but gives no server-specific notes.
