I've noticed that for some projects PTGUI 12.7 is extremely slow. The same project runs much faster on PTGUI 11.13 which I have on another PC.

FYI, the PC with 12.7 has an Intel i7-7700 CPU with 32GB RAM while the one with 11.13 runs on a tiny little notebook with an Intel i5-8265U CPU, 8 GB RAM and no dedicated graphics card (only an Intel UHD 620).

Still, despite the much slower PC, 11.13 is about three times faster than 12.7.

So can I install 11.13 on the big PC and use it when 12.7 is too slow?

Hi Alfred,

Please see 3.31:

PTGui 11 can still be downloaded here:

And see 3.29:

Kind regards,
