I'm curious - I recently replaced my six year old computer with a midrange one - mainly for Photography, Photoshop and Video editing - and thus I sort of neglected the GPU, with the goal to upgrade it later. At the time I settled for a low end Geforce GT 730 and it doesn't do well in iClone 7 at all unless I drop a lot of the settings to low, and even then performance is pretty bad all things considered. iClone 6 did slightly better, but I haven't used it heavily on the new computer. Since I'm not heavily into PC gaming, I decided to opt for a 4GB Geforce GTX 1050 ti which according to my research is fairly decent and should make a significant change...
The rest of my PC specs are :

AMD Ryzen  5 1600
16GB RAM
Windows 10

What are your PC specs? How does iClone 7 perform for you with all the bells and whistles turned on? I'd imagine the GI effects could choke some machines pretty badly...?
