Graphics: Improvement

I'd like to ask whether FlexSim has abilities to improve graphical output for the purposes of video capture.

I've noticed that models such as a simple rack [attached] as seen from a distance, appear to have jagged lines. I'm assuming this issue could be solved with antialiasing. I also recognize that FlexSim 2020 appears to have an RTX mode available under preferences although I'm unclear as to what it does.

Is there anything FlexSim could recommend for me to improve my graphical output?

-Are there settings I should use under global preferences?

-Is there a preferred 3D model file format? (the models I've imported *.3ds appears dark)

-Does computer hardware play a major role? (I assume not so much)

Any input is appreciated, thank you!

Capturing Video

Best Practices for Capturing Video in FlexSim

Jagged Lines

You're seeing jagged lines because your graphics card isn't straightening them out. Open the graphics control panel for your graphics card and turn up the anisotropic filtering and antialiasing.

RTX

From the User Manual:

RTX Mode (Beta)

Checking this box will cause the view to be rendered using Nvidia's OptiX ray tracing engine. This rendering mode is only available using 64-bit FlexSim on compatible Nvidia graphics cards and drivers.

Nvidia RTX graphics cards (Turing architecture) have RT cores that improve the performance of RTX Mode. Some older Nvidia graphics cards (such as Maxwell, Pascal, and Volta architectures) can work with RTX Mode with lower performance.

RTX Benefits

Improved shadows. All of the scene's light sources (including point source lights) can cast shadows, and the resolution of the shadows is not determined by rendering the scene multiple times into cascading shadow map textures. Each light can cast realistic hard or soft shadows depending on its settings.
Unlimited light sources. RTX Mode can use any number of light sources, although performance will decrease as the number of lights increases.
Order-independent transparency. Transparent meshes do not have to be drawn after other meshes when using RTX Mode, and the order of the triangles within a translucent mesh does not affect how it is rendered.
