For Isaac Sim 5.1, the minimum requirement is listed as an RTX 4080 with 16 GB of VRAM. My laptop has an RTX 5060 with 8 GB of VRAM. Would it still be able to handle basic tasks, such as building simple 3D scenes and testing code? For actual model training, I plan to rent a cloud GPU.
Hi @lethanhtaicute345 — short answer: it’ll launch and let you learn the UI, build simple scenes, and test code, but expect to hit VRAM limits quickly. The RTX renderer alone needs up to ~7 GB, so on 8 GB you have very little headroom.
For your plan (learn/prototype locally, train in the cloud) it’s workable if you keep scenes minimal. A couple of flags help:
./isaac-sim.sh --/app/content/emptyStageOnStart=true
and close other GPU apps. Treat it as a learning/dev box, not a place to run full workcells. The 16 GB minimum is real once scenes get realistic.
