UT supports a variety of 3D rendering options, though for consistency I chose Microsoft's DirectX D3D rendering engine for all tests. With the latest 4.36 patch installed, D3D actually proved more efficient than UT's native 3dfx GLide support. All tests were executed using the default configuration. The only settings changed between tests were color depth and screen resolution. The test scenario used for UT is the Reverend's Thunder test map.
Thunder scales well in higher resolutions and bit depths.
However, the situation changes at 1280x1024x16. The Voodoo 3, with its limited 16MB of memory and inability to perform AGP texturing, proved too slow for smooth game-play at this higher level. The TNT-2 Ultra did far better, as it includes more memory and AGP 2x texturing capabilities. The Siluro MX and GeForce-2 GTS scored rather well in all tests. The Siluro MX provided smooth playback with a minimum in frame stutter or stalling.
