I've done exactly the same question for IMSI/Desing support and got no response
, so I'm passing you on from my observation in a job I did recently.
I ran on a relatively new DELL workstation with two GPUs Quadro installed a moderately complex 3D design made on a desktop with a very old Geforce (GTX 550 Ti) and to my surprise the difference was very subtle both in handling and in rendering.
I expected a whole new experience but it was not significant.
Talking about the desktop with Geforce.
I work with two monitors and in one I left the task manager (Windows 7 64 Bits) in performance monitoring mode while working on the file to monitor the overall system demand.
What I could tell you is that my 8 CPU cores (i7 920 @ 3.4GHz) were used very little (on average) as well as GPU processing while the RAM was consumed at the speed with which the fuel of a jet with full power and post-combustor powered was consumed.
My 12Gb of RAM was not enough for fine rendering and I had to work a lot on the file so that I would achieve the desired effect on time. If I had around 32Gb of RAM I would have a coffee, watch a TV series while the rendering was running and after a few hours I would return. LOL
I do not believe that Nvidia has a partnership with IMSI and produces a video driver for TurboCAD like other software, just see that the price of TurboCAD compared to other CAD software is considerably lower.
What differentiates GPUs from the Quadro series of Geforce are precisely the dedicated, personalized drivers.
Let's not forget that one is dedicated to openGL (although it is also an API used in games is more dedicated to professional graphics work) and the other to directx.
Although I did not submit this question (It's good to do that) to REDWAY3D who is the developer of REDsdk, the 2D / 3D graphics API TurboCAD uses.
I realized that the amount of RAM and VRAM are the deciding elements for the TurboCAD and not the CPU or GPU, although obviously the higher the processing capacity the better.
So I chose to forget the GPUs Quadro and buy a GTX1070 / 1080 and double the amount of RAM on my system.
I personally know a designer with international awards and he uses Geforce.
CPU vs GPU??? ---> RAM and VRAM + CUDA cores = A happy day with TurboCAD
Hope this helps.
