VulkanFlow
VulkanFlow is a Fabric optimization mod for Minecraft 26.2 and 26.3 that adds shader-style visual effects while aiming to keep frame rates steady on integrated graphics.
What it does
Standard shaders loaded through Iris or OptiFine often drop the frame rate on integrated graphics, because the work is forced into a single frame. VulkanFlow takes a different route: it hooks into Minecraft's rendering pipeline, spreads the rendering load across several frames to smooth out spikes, and adds bloom-style lighting and gently swaying grass and leaves. The developer states the target as steady 60 FPS on integrated graphics like the Intel UHD 620, with the mod checked on a ThinkPad T480 laptop.
The mod is built for laptops and older PCs with weak graphics hardware. It can run standalone or alongside Sodium, and it keeps an OpenGL fallback for the Vulkan rendering path. Dynamic shadows and custom water are listed by the author as planned features still in active development. Iris or OptiFine is listed as a requirement in the author notes, so that shader-based setup is needed for the effects.
Key features
Glowing light sources
Light sources such as torches and lanterns get soft, cinematic glows rendered with a bloom-style effect.
Swaying grass and leaves
Grass and leaves move gently in the wind, adding motion to outdoor scenes without a full shader pack.
Time slicing
The rendering load is distributed across multiple frames, which the author describes as a way to smooth out frame spikes.
Vulkan path with OpenGL fallback
The mod hooks into the Vulkan rendering pipeline and keeps an OpenGL fallback for systems that need it.

What the author says
Welcome to VulkanFlow! This mod integrates Shader effects directly into the Minecraft rendering pipeline without destroying your framerate. It is made for players on laptops or older PCs that just want to play shaders without playing on really low fps. I made this mod because I wanted to play with Shaders on my iGPU…
