Steam Deck Performance Optimization 2026: Core BIOS & System Tuning
To begin your Steam Deck Performance Optimization 2026 setup, boot into the BIOS menu by holding Volume Up and Power. Under Advanced Settings, change the UMA Frame Buffer Size from the factory default of 1GB to 4GB, preventing memory crashes in high-VRAM games like Cyberpunk 2077 and Forza Horizon 5.
Next, install CryoUtilities via Desktop Mode to configure a 16GB swap file on your internal NVMe SSD and enable Huge Pages memory compression.
