How powerful is Unity?

Hello. I am new to Unity and I am going to be asking a lot of questions. First I was wondering how much can do with Unity. How many tris can you have before it is too much. Can it take high quality texturing. How big of a map can you have. This is all for pc development. Also I was wondering if anyone has advice for good C# tutorials. Thank you very much for your time.

Generally, the limitation will always be your graphics card, not Unity. Unity can deal with quite a lot at the same time: millions of polygons, several scenes, hundreds of scripts and whole script frameworks, high-resolution textures up to 4096x4096.

Our main project has about 9000 assets, the standalone build consists of 42 scenes with 30-40 4096x4096 textures, several terrains with detailed height maps, hundreds of models, shader effects, you name it. The build size of it is 2.7GB, mainly caused by textures, but also terrains, models, and videos.
While working, the editor process rarely exceeds 2GB RAM.

i guess tri-limit depends on your machine

You should research the site, YouTube, and other topics related to Unity’s capability along with high-quality games that have been created using this engine.

All that you have asked, the answer is yes. The game can be pretty damn big and detailed. The maps can be enormous. But, keep in mind, size isnt really a factor when it comes to how much you want to put in. You can scale the game to a fraction.

Some of your best tutorials in C# can be found on Unity’s resource site. It has descriptions and examples of their pre-defined functions and methods.

Thank you all very much. Just wanted to understand more and I really like how fast the question was answered. Thanks again.
