I am a little dissapointed by my recent discovery.
I have recently re-rendered an old project of mine, back from 2014 and the entire process took about 3 hours (no PT), which is perfect.
However, renders of similar complexity done with new projects in Terragen 4 take 8 to 11 hours (no PT).
This is why I don't trust the professed "faster rendering" assurances that the main page displays.
I wonder if there are any changes or settings involved that make old projects render like a dream...? Whether anything else created with TG 4 seems to take forever to complete. This is quite disappointing...
My hardware is in good condition, so this is not the cause. CPU is (a slightly overcloked) 2.9Ghz i7, paired up with 16GB RAM.
