Hi
What has your pc spec increased from?
What was changed?
Remember that render times are dependent on a. plethora of factors e.g timeline duration, type of effects used, motion blurs etc, footage res (if used), etc etc so we need to look at :
1. What your project is i.e what is on the timeline
2. Comp settings
3. Output module settings
Post screen grabs or a vid if possible and we will work from there
