+# Versteckte Grafik-Features in der Q3Rally-Engine (Code-Audit)
+
+## Methode
+- Als **sichtbar im Menü** gelten Cvars, die in `ui_video.c` (Graphics) oder `ui_advanced_graphics.c` (Advanced Graphics) gesetzt/gelesen werden.
+- Als **versteckt** gelten Renderer-Cvars aus `renderergl1/tr_init.c` und `renderergl2/tr_init.c`, die in diesen Menüs nicht auftauchen.
+
+## Bereits im Menü sichtbar (nicht versteckt)
+- Klassisches Grafikmenü: Auflösung/Fullscreen/Farbtiefe/Texturebits, LOD-Geometrie, Texture-Filter, Aniso, MSAA, Sun Shadows + Shadow Quality. 
+- Advanced-Menü: HDR, PostProcess, ToneMap, AutoExposure, SSAO, Sun Rays, Dynamic Reflections.
+
+## Versteckte Features (nicht im Grafikmenü)
+

+- `r_pshadowDist`
+- `r_ext_framebuffer_object`
+- `r_ext_texture_float`
+- `r_ext_framebuffer_multisample` (wird teils intern gesetzt, aber nicht als eigenes UI-Feature geführt)
+- `r_arb_seamless_cube_map`
+- `r_floatLightmap`
+- `r_depthPrepass`
+- `r_mergeLightmaps`
+- `r_imageUpsample`, `r_imageUpsampleMaxSize`, `r_imageUpsampleType`

+- `r_vaoCache`
+
+### 3) Atmosphärisch/„Look“ (situativ)
+- `r_forceSun`, `r_forceSunLightScale`, `r_forceSunAmbientScale`
+- `r_drawSun`
+- `r_dynamiclight`, `r_dlightBacks`, `r_dlightMode`
+- `r_fastsky`

+- `r_inGameVideo`
+
+### 4) Performance/Kompatibilität/Präsentation

+- `r_maxpolys`, `r_maxpolyverts`
+- `r_stereoEnabled`, `r_stereoSeparation`, `r_anaglyphMode`
+
+### 5) Debug-/Diagnose-Cvars (keine echten Upgrade-Hebel)
+- `r_showImages`
+- `r_debuglight`, `r_debugSort`
+- `r_measureOverdraw`
+- `r_logFile`, `r_verbose`
+- `r_printShaders`, `r_saveFontData`
+- `r_offsetfactor`, `r_offsetunits`, `r_drawBuffer`
+- `r_ignore`

+- `r_uifullscreen`
+
+
+## Schatten-spezifischer Gap zum **ADVANCED GRAPHICS** Menü
+
+### Bereits abgedeckt (aber im klassischen Graphics-Menü, nicht in Advanced)
+- `r_sunShadows` (On/Off)
+- `r_shadowFilter` (indirekt über Shadow Quality)
+- `r_shadowMapSize` (indirekt über Shadow Quality)
+
+### In Advanced Graphics **noch nicht integriert**
+- `r_shadowBlur`
+- `r_shadowCascadeZNear`
+- `r_shadowCascadeZFar`
+- `r_shadowCascadeZBias`
+- `r_pshadowDist`
+- `r_sunlightMode`
+
+### Einordnung
+- Derzeit steuert `ui_advanced_graphics.c` nur post-processing-nahe Features (`r_drawSunRays` etc.), aber keine dedizierten Shadow-Cascade/Blur-Parameter.
+- Schatten-Controls liegen heute primär im klassischen `ui_video.c` (Sun Shadows + Quality-Mapping auf Filter/MapSize).
+

+
+## Kurzfazit
+Die größten Hebel für ein sichtbares Grafik-Upgrade liegen im GL2-Feature-Block: Materialsystem (Normal/Specular/Parallax/PBR), Schatten-Kaskaden + Blur, Cubemaps/Reflections sowie Upsampling/Lightmap-Pfade.
