Silva Pro Shaders pour Minecraft 1.20.1, 1.21.1

Silva Pro

Silva Pro is a lightweight Minecraft shaderpack designed to deliver modern, atmospheric visuals without demanding high-end hardware.

The shader focuses on realistic lighting, soft shadows, natural atmospheric scattering, improved water, procedural clouds, cinematic post-processing, and smooth performance across low-end, integrated, and mid-range GPUs.

Silva Pro uses an optimized GLSL 1.20 pipeline compatible with Iris and OptiFine, keeping the shader accessible to older hardware while still offering higher-quality rendering options for more powerful systems.

Performance

Silva Pro is built around scalable rendering.

Lower quality levels reduce expensive shader operations such as shadow samples, SSAO samples, SSR steps, cloud detail, and atmosphere integration. Higher quality levels progressively increase visual fidelity for hardware with additional GPU headroom.

This allows Silva Pro to provide a good visual upgrade even on integrated graphics while still offering advanced rendering features for stronger systems.

Compatibility

• Iris
• OptiFine
• GLSL 1.20 / OpenGL 2.1+
• Minecraft 1.16+ through modern versions
