When users ask about FPS optimization, present DVARs sorted by impact (high → medium → low). For each high-impact DVAR, suggest a safe FPS-boosting value:
| DVAR | Default | FPS Value | Impact |
|---|---|---|---|
com_maxfps | 85 | 0 (uncapped) or 250 | high |
r_vsync | 0 | 0 | high |
r_aaSamples | 2 | 1 | high |
r_picmip | 0 | 2-3 | high |
sm_enable | 1 | 0 | high |
sm_sunEnable | 1 | 0 | high |
r_glow | 1 | 0 | medium |
r_distortion | 1 | 0 | medium |
r_dof_enable | 1 | 0 | medium |
r_specular | 1 | 0 | medium |
r_texFilterAnisoMax | 4 | 1 | medium |
fx_drawClouds | 1 | 0 | medium |
ragdoll_enable | 1 | 0 | medium |
dynEnt_active | 1 | 0 | medium |
cg_brass | 1 | 0 | low |
fx_marks | 1 | 0 | low |
r_drawDecals | 1 | 0 | low |
Present results in a clear table format:
| DVAR | Type | Default | Category | FPS Impact |
|------|------|---------|----------|------------|
| r_fog | bool | 1 | renderer/fog | medium |
Include the description for enriched DVARs. For DVARs without descriptions, the name and category usually make the purpose clear.
