Nothing wrong with having lots of customization and settings regarding the game engine itself, but too much might be just for the average user (unless documented good) Max visible players should be the same for everyone. Other settings like texture-quality and viewdistance are better options to allow less powerful computers to work.
There is many ways to optimize and speed up your framerate - cutting players from your view is definitely NOT what we are aiming for. There is quality setting on the characters that can be turned down (texture size, amount of triangles, animations, etc) which lead to the same effect than just simply removing more models from your view. Also, to clear this up again, we want to be able to show 1000 players when you do a 360-view, meaning about 250 characters in every direction (assuming a 90 degree view angle), which believe me, is way more than you have seen in most games so far, and is actually way more than you can actually 'see' and 'react' to...but that's for another video/demo to show maybe! the point I want to make is, you will be able to see everything that is important for you, and if your gaming rig is equal or better to our minimum requirements, then you should be fine to see that in a playable quality!
For this reference: LoL had highest AT THE SAME TIME PLAYING people around 1.5 million or so *had the link somewhere* could had been also "only" 1.2 million But anyway I think everything else regarding server stability etc. was said by Mr. Balthazar and the others already
