I am new to photogrammetry and have been reviewing forum posts and watching YouTube videos. I keep seeing references to "CUDA GPU". I understand that these graphics cards will improve performance but is one a necessity to use 3DF Zephyr? I want to try out 3DF Zephyr Free but would like to wait until I get some experience before upgrading my PC. Advice needed. Thank you.

Hi Scanner72, welcome!

Using an NVIDIA card (thus allowing to use CUDA technology) you can speed up significanly the processing using your graphic card.

If you don't have a cuda capable card, or if you don't have an nvidia card, you won't be able to use this speed up. Zephyr will still work in CPU only, but it will be significanly slower.
