Ah OK, I misunderstood there. (Although if you do ever have some money spare, a GPU upgrade will kick a bit more life into any older PC)

Since there is no option in the settings mentioning it you'll have to assume that there's no way to control this in Muvizu unless you hear differently from the staff. As long as you've enabled it in your GPU settings it should be fine.
Muvizu should render as fast as possible - the main selling point of it is the ease and speed, after all. Have you got any comparative timings for tga vs avi?

I wish you luck in your codec research but I'm still persistent that tga is the only serious way to export movies from Muvizu.

Using the VRAM is a basic requirement of a graphics card surely?

Yup, but only usually for textures and 3D models, not video rendering and such - CUDA lets you use the faster VRAM (rather than your system's slower DRAM) to process this stuff to give a modest performance boost, but nothing so dramatic it's a game changer or anything.

you will notice cuda tech differences with certain things and I recently found out that for certain things nvidia and adobe got together to do some underhanded stuff regarding cuda tech. For instance the cuda tech exists on the 980 & 970 cards and is identical in speed to the titans, but they have partially disabled it to try to pressure people to purchase the titans.

Anyhow it does make a noticable difference with dealing with 3dstuff the amd cards make me wanna tear my hair out when using things like 3dcoat or other types of software but really I dont think it makes a huge difference with regards to muvizu because of what it is. However it makes larger difference elsewhere and I as a result purchase cards with it but tend to stay away from companies like adobe that has worked with nvidia to try to sell the titans. Not a fan of what nvidia has done regarding that but I need a good pc and unlike software so far I am left bowing down to nvidia because of this tech.

so if you like adobe after affects for instance or hitfilm your gonna want a card with cuda tech. It also makes a huge difference with iclone6 cause of how it works, but here not so much as muvizu is not as new and so it doesn't really tap into it a huge amount. (sorry used an evil word on this board but if your looking to progress and use your card for more then just muvizu and your doing 3d and particles and using voxel tech blah blah blah.. your gonna want a card with cuda)

Also, to import the targa sequence into sony vegas you have to check this box after selecting the first frame:

The one time I tried this Targa funny business and I imported into Vegas, it ran the video backwards. I'm guessing it's because I didn't have this checked?
