The following lists the suggested maximum amount of triangles that should be allowed to draw per scene.

Multiplayer Levels: 50,000 triangles

The values listed are a general guideline due to the fact that performance is affected by many factors other than triangle counts such as the number and type of materials (shaders) in the scene, sounds, dynamic lights, lens flares, and other game objects.

As can be expected, the fewer triangles being drawn the better. When creating a level, the level designer should always take into the account additional triangle counts added by vehicles, players, weapons, items, and effects and prepare for any worst case scenarios in terms of triangle counts and rendering.
