🎮 Hardware & Performance

Q: Which GPU is best for AI upscaling?

A: Performance ranking:

1. RTX 4090/4080 - Best (DLSS 3.0, 4K upscaling)
2. RTX 3080/3070 - Excellent (DLSS 2.4, 1440p-4K)
3. RX 7900 XT/7800 XT - Very Good (FSR 3.0, 1440p-4K)
4. RTX 2070/2060 - Good (DLSS 2.0, 1080p-1440p)
5. RX 6700 XT - Good (FSR 2.1, 1080p-1440p)

Q: How much VRAM do I need?

A: VRAM requirements:

• 6GB: 1080p upscaling (minimum)
• 8GB: 1440p upscaling (comfortable)
• 12GB+: 4K upscaling (recommended)
• 16GB+: 4K+ with all features (optimal)

Q: Why is my performance bad?

A: Common causes and fixes:

{
  "high_gpu_usage": "Reduce scale factor from 4x to 2x",
  "overheating": "Improve cooling, reduce quality settings",
  "low_vram": "Lower resolution, disable HDR enhancement",
  "cpu_bottleneck": "Upgrade CPU or reduce CPU-intensive features"
}

Q: Can I use multiple GPUs?

A: Currently, the plugin uses the primary GPU only. Multi-GPU support is planned for future versions.

🎬 Video Quality & AI Methods

Q: Which AI method should I use?

A: Choose based on your content:

• Movies/TV Shows: Real-ESRGAN or DLSS
• Anime: Waifu2x-cunet (specifically designed for anime)
• Gaming/Streaming: FSR (best performance/quality balance)
• Old Content: Real-ESRGAN (excellent for restoration)

Q: What's the difference between DLSS, FSR, and XeSS?

A:

Method	Hardware	Quality	Performance	Best For
DLSS	NVIDIA RTX only	Excellent	Best	Gaming, Movies
FSR	Any GPU	Very Good	Good	Universal compatibility
XeSS	Intel Arc best	Good	Good	Intel systems
Real-ESRGAN	Any GPU	Excellent	Slower	Photo-realistic content

Q: How much quality improvement can I expect?

A: Typical improvements:

• 720p → 1440p: +6-8 dB PSNR, very noticeable
• 1080p → 4K: +4-6 dB PSNR, significant improvement
• 480p → 1080p: +10-12 dB PSNR, dramatic transformation
• Old content: Noise reduction + detail enhancement

Q: Why does anime look weird with some AI methods?

A: Use Waifu2x-cunet for anime! Other methods are designed for photorealistic content and can make anime look unnatural. Waifu2x preserves the art style.
