Here is an easy way on how to speed up your Sony Vegas rendering speed up to 45% or more! However, this relies on an external hardware which is your external graphic card, not the IGPU (Integerated Graphic Processing Unit) that is pre-built within your Intel/AMD CPU (Central Processing Unit). If you have a higher-end card you will gain more benefits from it!
Step by Step Guide:
1) Open Sony Vegas.
2) Go to “Options” > “Preferences”.
3) Click “Video” Tab.
4) Set “GPU Acceleration of video processing” : NONE > “Your Graphic Card”
Currently I’m running on MSI GTX 760 TF OC 2GB Graphic Card.
Therefore, the drop-box only shows 2 options which are:
a) None
b) NVIDIA Corporation (GeForce GTX 760)
