Using Vegas Pro 12. On my old machine, it works flawlessly, got a new pc, Dell with an Intel Xeon CPU-E5_1630 v3 @3.70 GHz and 32 GB RAM and a NVIDIA k2200 card. If I render something, it will almost certainly crash. Take out the audio tracks, and it's fine. Same with just previewing footage. Also if I render just a 1 minute wav file, it takes several minutes, where on my old system, it would have taken seconds. I'm sure I'm missing something setting wise here. Tryed changing the audio devise type, experimented with buffering, updated all my drivers....no help. Any suggestions?
