Speed up tip for slow rendering

PostWed Apr 11, 2018 7:20 pm

I did quite a bit of searching but didn't see this answer.

It might be obvious to some, but it took me some trial and error.

I was only making some 150 frame text animations and thought they wouldn't be too large, so I had the output file sent to desktop so I could do some formatting after.

I was experiencing horribly slow rendering times, after several runs, as high a 3 mins per frame with 79% CPU and 7.9 GB RAM usage.

I switched to a secondary hard drive as my output and voila, as high as 2 FPS, 55% CPU, and only 5 GB RAM usage.

After about 3 or four animations, it would bog down a bit and a restart cured it.

It does seem to close slowly even though the interface closes quickly, it doesn't release the RAM for sometimes 5 minutes or more.

Overall though, writing to a secondary drive is a real timesaver.

I hope that helps someone. It would have saved me about 4-6 hours troubleshooting and running several renders at a snail's pace.

If anyone knows a solution to why it gets progressively slower the more renders you do or how to close out the program faster and release the RAM, please let me know.
