DLSS / FSR Not Working or Looking Bad
What is this error?
NVIDIA DLSS or AMD FSR upscaling is not available, not activating, or producing blurry/artifacted output.
Common causes
- GPU doesn't support DLSS (requires RTX)
- DLSS/FSR set to wrong quality mode
- game needs update for latest DLSS version
- running at native resolution (upscaling has no effect)
- frame generation causing visual artifacts
How to fix it
- Check GPU compatibility
- set correct quality mode
- swap DLSS DLL for newer version
- ensure render resolution is below display resolution

DLSS and FSR upscaling issues — not available, greyed out, blurry, or causing artifacts — have specific fixes.
DLSS not available:
- DLSS requires an NVIDIA RTX GPU (RTX 2060+). GTX cards can't use DLSS
- Make sure the game is running in DirectX 12 mode — most DLSS implementations require DX12
- Check if the game supports DLSS at all — not all games do
DLSS looking blurry:
- Set DLSS to 'Quality' mode, not 'Performance' or 'Ultra Performance'
- Enable DLSS Sharpening in the game's settings
- Swap the game's DLSS DLL for a newer version: download the latest nvngx_dlss.dll from TechPowerUp, replace the one in the game folder — newer DLSS versions look significantly better
- Make sure the game's render resolution is actually being upscaled — some games disable upscaling at native resolution
FSR looking bad:
- FSR 1.0 (spatial) looks much worse than FSR 2.0+ (temporal). Check which version the game uses
- Set FSR to 'Quality' mode minimum
- FSR works on any GPU (AMD, NVIDIA, Intel) — if it's greyed out, check if it requires a specific DirectX version
Frame Generation artifacts:
1. DLSS 3 / FSR 3 Frame Generation can cause ghosting and artifacts — disable it if visual quality matters more than FPS
When to seek help
If this error keeps happening after trying the fixes above, it may point to a deeper hardware or system issue. Consider professional help if:
- The crash occurs across multiple games or applications
- You see the same error after a clean Windows install
- Your PC is less than a year old (could be a warranty issue)
- You smell burning or hear unusual sounds from your PC
