GPUs and Sony Vegas

I had picked up a GTX 650ti a while back, and was pretty disappointed that in tests, it seemed to do nothing for rendering. If you enabled it fully, it just causes Vegas to crash completely. I have read that Radeon based cards work much better. Curious to know if anyone has confirmed this, experienced any real benefit, and what model card they used if so.

You could search for posts of mine and oldsmoke's for discussion at length. Basically get an AMD card with an XT chip or x series of card for the best performance with opencl encoder abled.

Opencl does more than speed up avc redering, it enhances the compute performance of your system with certain types of math. That said you are not going to see some codec use 100% of the gpu. If you get the right gpu you will see a boost in playback and rendering that require compositing and effects. You will see the most gpu usage when working with 32-bit floating point projects.

Your 7970, 290x, 390x, and FuryX are going to be your best cards for general 8-bit vegas work. Some cards are on ebay these days, others you can still get new.

Always get the latest build of Vegas 13, and the latest drivers for the card.

You can use something like Luxmark to verify that opencl is working correctly.

I can confirm that after switching my home and work systems from nVidia to ATI the crashes stopped, rendering was improved and - most important to me - timeline playback went from 12 - 15fps to real time with 1080p AVC or MP4 camera footage at Good (Full) or Best (Full) quality with transitions, color correction, and audio processing. My system specs are posted if you want details.

Hopefully Magix will fix NVidia GPU compatibility. If I remember correctly the last NVidia cards to work with Vegas reliably were the GTX 500 range. The 500 range were great for their time but are completely untenable for those of us who use 3D modelling and other modern resource intensive GPU driven software along with Vegas. The latest GTX1080 is more powerful and a lot cheaper than a Titan X hence the frustration at current NVidia/Vegas incompatibility.
