Hey lef80 ,
Thank you for sharing your thoughts!
Please keep in mind Enscape is still a real-time rendering engine, so complexity of your models and textures has an effect.
If you fill your model with lots of high-detail, high-poly models and high-resolution textures, ANY graphics card will have troubles executing it fluently. This is probably where your noise comes from.
Also, smart idea to proxy the high detail models, but this will only improve your SketchUp performance. The Exe Standalone produced by Enscape still has to contain all the models in full quality, all textures, and also the Enscape Engine and 3D assets, so that's why it wouldn't help.
To answer your questions:
1. We can't just increase the web standalone quality anyway we wish. First, it's written in an entirely differen system (WebGL) than Enscape, so we don't have the same tools to craft the same high quality. But this is also the reason why it can run in a browser. If we were able to achieve the same quality in the Web Standalone, it wouldn't perform any better than regular Enscape, either.
2. Thank you for your feedback. I have added your vote to our internal system.
For corona-compliant user meetings, have you thought about holding a web meeting with your clients and sharing your screen while showcasing Enscape?
Not the fanciest, but a very viable solution.
