Glimmer vs Wispy Shaders

Glimmer has no write-up on Specifiction yet; its figures are above.

Wispy Shaders is a Minecraft shader pack designed to limit performance demands, with particular attention to integrated graphics. It began from Mellow Shaders and offers five profiles, from Ultra Performance through Ultra Quality, so players can select a balance of speed and image treatment. The pack provides color grading and lighting tailored to biomes in all dimensions. Its post-processing options include bloom, sharpening, tonemapping, TAA, motion blur, and vignette. The maker also lists optimizations across gamma correction, composite passes, fog, lighting, sky, water, and other shader processes. Wispy is free and supports Minecraft Java Edition versions 1.8.9 through 1.21.x. It requires Iris Shaders or OptiFine; installation means placing the ZIP in Minecraft’s .minecraft/shaderpacks folder. The maker reports a 40%+ Balanced-profile improvement over MakeUp-Ultrafast with all effects off, based on V1.3. More benchmarking remains planned, with some discrete-GPU profile results unknown.
