I have been using D5 in my laptop, an Asus Zenbook Duo with an Intel Core Ultra 9 185H, (no GPU).
Ir worked fine for 6 months. It showed some minor and expected lagging with bigger models but never froze or crashed. Since the last update 2.10.2 it makes my laptop freeze afer a few seconds after loading a model, with or without livesync from sketchup. The laptop stays frozen until a hard reset. I haven’t changed any settings.
Although there are a few instances where devices with no Dedicated GPU work with D5 momentarily. We do not suggest it since D5 is reliant on the device’s dedicated GPU, and forcing it to run with only an Integrated GPU may cause serious device complications and irreversible damage.
D5 Render is a real-time raytracing rendering tool, thus requiring a raytracing-ready GPU and operating system. The graphics card has a direct impact on real-time smoothness and output time, but not on output quality. Video memory determines the performance of handling complex scenes.
