Applied comprehensive corrections from Discord community (DeathStalker, Astrocast, and others) to fix inaccuracies, remove outdated procedures, and improve readability. CRITICAL SAFETY FIXES: - IOMMU: Changed from "optional" to "MUST disable" across all docs - Removed dangerous `amd_iommu=on` kernel parameter (causes crashes) - Added danger warnings that IOMMU is broken on BC-250 BIOS & VRAM FIXES: - Fixed BIOS flashing guide: removed fake "ZIP file" references - Added link to actual flasher utility (separate from ROM download) - Removed made-up Windows utility steps, added real ASRock method - Removed AMIBCP/Smokeless section (not used, P5.00_clv has all unlocked) - VRAM docs: reduced verbosity by 40%, emphasized 512MB is DYNAMIC - Added ZRAM conflict warning (crashes in RDR2 with dynamic VRAM) COOLING & HARDWARE: - Removed impractical fin cutting/screwing instructions - Removed J4003 header references (not for normal users) - Added tower cooler downside (must cool VRAMs separately) - Static pressure already correct at 6.9 mm H2O LINUX DISTRIBUTION UPDATES: - Fedora: Removed outdated setup script, Mesa 25.1 now in repos - Fedora: nomodeset no longer needed on 42/43 with working kernels - Bazzite: Removed "on steroids" section (patch included by default) - CachyOS: Simplified from custom ISO to standard installation - Updated KDE vs GNOME: GNOME recommended for stability (6 changes) - SteamOS/Ubuntu: Already added in previous commit (verified) GOVERNOR & DRIVERS: - Prioritized COPR installation over building from source - Added @exotic-soc/oberon-governor and filippor/bazzite repos - Display adapters: Now recommend PASSIVE (audio works) over active IMPOSSIBLE FEATURES REMOVED: - Fortnite: Clarified it cannot run (Easy Anti-Cheat) - ROCm training: Corrected to "experimental/limited" (doesn't work) Desktop Environment: GNOME now recommended over KDE for stability (KDE had Qt RDSEED bug, now fixed but GNOME more tested) Files modified: 14 Community credits: DeathStalker, Astrocast, legodude

Game-Specific Tweaks
Improve Stuttering
Check shader caching:
- Steam pre-compiles shaders
- Wait for shader compilation before playing
- Can cause initial stuttering
Increase shader cache size:
# Add to /etc/environment
__GL_SHADER_DISK_CACHE_SIZE=10737418240 # 10GB
Fix Audio Clicking
Some games have audio issues:
- Try different Proton versions
- Use Proton-GE
- Check game-specific ProtonDB reports
Resources
ProtonDB
Check game compatibility: protondb.com
- Community reports on Linux compatibility
- Specific BC-250 performance may vary
- Look for similar AMD GPU reports
Are We Anti-Cheat Yet
Check anti-cheat compatibility: areweanticheatyet.com

Performance Expectations
vs. PlayStation 5
| Aspect | BC-250 | PS5 |
|---|---|---|
| CPU Performance | 75% | 100% |
| GPU Performance | 67% | 100% |
| Real-World Gaming | 70-80% | 100% |
Summary: Expect slightly lower performance than PS5, but still very capable for 1080p gaming.
vs. Desktop GPUs
Approximate Equivalent:
- Rasterization: Between RX 6600 and RX 6600 XT
- Ray Tracing: Similar to RX 6600
- Memory: 16GB total (split), vs 8GB dedicated
Tips for Best Experience
- Use FSR: Free performance boost in supported games
- Install Governor: Essential for dynamic frequency scaling
- Update Mesa: Always use Mesa 25.1.3+ for best compatibility
- Try Proton-GE: Better compatibility than stock Proton
- Monitor Temps: Keep GPU < 85°C for stability
- Adequate VRAM: Use 4GB split for AAA games
- Disable Mitigations:
mitigations=offfor +10-15% FPS - Optimize Kernel: Use 6.15.7-6.17.7 or 6.12-6.14 LTS, avoid 6.15.0-6.15.6 and 6.17.8+
