GPU Text Rendering for Unity / VRChat
Render 32 texts in 1 draw call with high quality. Fully GPU-driven, no C# runtime required.
Fragment shader instruction counts (Unity compiled shader stats, d3d11):
| Math | Texture | Branch | |
|---|---|---|---|
| Typography | 920 | 3 | 31 |
| SSVFX | 3,702 | 102 | 201 |
| TexSvfx | 5,585 | 210 | 255 |
1/4 fragment instructions vs alternatives. Processing concentrated in Vertex Shader - performance gap widens with resolution.
| Avg | Ratio | |
|---|---|---|
| Typography | 0.471ms | 1x |
| SSVFX | 0.851ms | 1.8x |
| TexSV | 6.094ms | 13.0x |
