First of all, the most important info is missing: your graphics card brand & model.
Secondly, AntiAliasing enabled is a frame rate killer in any 3D application.
And Finally, statements such as "I got 200 FPS" are suitable for teenagers,
because in the "real world" your're limited by the monitor refresh rate (in most of the cases 60-75 Hz).
In other words, you cannot see more than 60-75 frames per second no matter what's your FPS value.
Thank You for your reply.
Good new for me is "AntiAliasing enabled is a frame rate killer in any 3D application"
I didn't know about monitor limitations too.
But still my "200 fps" isn't about how much my eye can see but how much my processor can do without Anti-aliasing.
So... I'm still at the same point.
How to get Anti-aliased (or pseudo-AA) models in any faster way?
Im using D11 and graphic card is not important because I want to have this effect on any computer.
Any Ideas please ?
That's the main problem: the graphics card is VERY important here!
For example if your 3D world contains 20 spheres, but each sphere has 5000 faces (polygons),
it means 100,000 polygons per 3D world.
The performance drop in case of AA enabled is significant, and you need a top graphics card to get a decent frame rate.
