Troubleshooting
Slow Generation Times
Learn why generation might be slow and how to improve speed.
Expected generation times
Typical generation times:
| Scenario | Expected Time |
|---|---|
| Standard render | 10-30 seconds |
| Complex scenes | 30-60 seconds |
| High server load | 1-2 minutes |
Why generation might be slow
Server load
Our AI servers may experience high demand during peak hours, which can increase wait times.
Peak hours (US Pacific Time):
- Weekdays: 9 AM - 5 PM
- Early morning and late evening are typically faster
Solution: If possible, try generating during off-peak hours.
Complex prompts
Longer, more detailed prompts require more AI processing time.
Solution: Start with simpler prompts and add detail as needed.
Large reference images
Uploading large reference images increases upload and processing time.
Solution: Resize reference images to under 2 MB before uploading.
Network connection
A slow or unstable internet connection affects both upload and download speeds.
Solutions:
- Check your internet speed (recommended: 25+ Mbps)
- Try a wired connection instead of WiFi
- Restart your router
- Move closer to your WiFi router
Troubleshooting slow generation
Check your connection
Test your internet speed at speedtest.net. If speeds are low:
- Restart your router/modem
- Try a different network
- Check if other applications are using bandwidth
Simplify your request
Try a basic test generation:
- Use a simple prompt: "Modern house exterior, sunny day"
- Don't upload reference images
- Use default settings
If this generates quickly, gradually add complexity to identify what's slowing down your normal workflow.
Check service status
Visit status.fastrender.ai (if available) or our Discord for any service announcements.
Timeout errors
If generation times out (usually after 2-3 minutes):
Wait and retry
- Wait 5-10 minutes
- Try generating again
- Don't send multiple rapid requests (this can increase queue time)
Contact support
If timeouts persist, contact hello@fastrender.ai with:
- Your account email
- Time of the issue
- What you were trying to generate
Tips for faster generation
- Use preset prompts — Optimized for quick generation
- Avoid peak hours — Try early morning or late evening
- Simplify descriptions — Shorter prompts process faster
- Optimize reference images — Keep under 2 MB
- Stable connection — Use wired internet when possible
Generation queue
Requests are processed in order. If many users are generating simultaneously, your request waits in queue.
Credits are NOT deducted for failed or timed-out generations.
