I just got back into Terragen as I have a new computer and thought I"d get better result times. While renders are faster, while rendering, my computer continuously locks up for moments at a time. This has never happened in the past except when a render is finishing it will briefly lag while it does it's last ambient occlusion (?) pass. Sometimes it'll lock up if the preview is open while working in PFs as well, so I have to pause the preview always which I also used to never really do.
I have a AMD A10 which is a APU, but the GPU is as disabled as possible for use with a RX 480 Nitro+ 8gb.
Is Terragen more demanding now? I mean, I didn't even have issues with it back on a AMD K7 series with 512mb RAM with TG2. Or even my 2004 Xeon X5450 with 4-8GB RAM, which I did use Terragen 4.0 on.
Update: As a note, this wasn't an issue with Terragen 4.0 which I just updated to 4.1.
