Here's a sample from my current project. Since I don't own the paid version I'm using the free version, too. There are no shaders involved as well here.
But you're able to achieve something like this, and even better graphics without slowing down the engine. As you can see I've got over 500 fps. (top right corner). And I wouldn't call myself a level designer to be honest. Just did some models, some textures and copied some effects I saw in a bunch of games I played. I work all by myself. Programming, models, levels, textures, sound, story and character design.
This runs on a 2 year old notebook by the way.
And don't get me wrong. I don't think I'm the super hero with the amazing work. There are a lot people in this forum with awesome skills. I consider myself not even as intermediate. I just wanted to give you an idea of whats possible with the free version
