3DMark Demo is a benchmarking demo for testing a PC and comparing results with friends on Steam. Rather than a conventional game, it offers a set of performance tests under the 3DMark name, making measured system results the focus.
Its listed benchmarks include Steel Nomad and Steel Nomad Light, alongside Solar Bay and Solar Bay Extreme. Time Spy and Fire Strike round out the selection, giving the demo several named tests to run on a PC. The range of benchmarks is a defining part of the product: users can test their system with different benchmark titles rather than relying on a single test.
After running a benchmark, users can compare scores with friends on Steam. That pairing of local PC testing and social score comparison gives 3DMark Demo a straightforward purpose: produce results, then see how they stack up among friends. The exact scope of the demo should not be assumed to cover every feature of the broader 3DMark product.
