First off, specs pc and laptop:
4GB of DDR3 RAM, dual channel.
GPU rendering is turned off but: Radeon HD 5850
Intel Pentium T4500
3GB DDR2 RAM
GPU rendering also turned off: ATI mobility radeon HD 4330
The project/render settings do not matter in this case, it concerns several different projects and for testing the exact same project and render settings were used on both laptop and pc.
Now for the problem: I've been trying to render several (small, 1-2 minute, not alot of videofx) projects on my pc and not one has completed succesfully. I can best describe what happens by displaying the test results. I took the exact same project (1440x1080, 25 fps, 1.10 minute, EXACT same render settings) on my PC and laptop and started rendering it at the same time.
- The laptop was done in 20 minutes, RAM usage for laptop stayed around 2.1-2.3GB used, CPU usage started at 100% and stayed 98-99-100%.
- By the time the laptop was done the pc was only at 30%, RAM usage started around 2.5 and slowly worked it's way up to full 3.9GB, CPU usage varied from 10%-30%, sometimes peaking at 90% in 1 or 2 of the cores. By the time the pc got to full ram usage it became unuseable and the rendering had (gradually) slowed down to about 1%/hour (understandibly I cancelled the render).
Can anyone shed some light on this issue? Any ideas/suggestions? It would be much appreciated.
