Halo utilizes pixel shaders 2.0, which is why the RADEON 9200 could not participate in this test.
Since the game is flooded with pixel shaders and variety of special effects, higher-end offerings from S3 Graphics demonstrate pretty competitive results due to 8 pixel and 4 vertex pipelines.
S3 DeltaChrome S4 Pro that has only 4 pixel pipes cannot provide minimally desired frame-rate at all. This crash is conditioned by pretty low core-clock along with inefficient architecture. It seems that modern games with realistic graphics and stunning effects cannot work fast enough on the DeltaChrome S4 Pro.
