We tested supercharging the RTX 5090 in PhysX games using an RTX 5060 as a secondary GPU — SLI may be dead, but how much can dual GPUs boost performance in classic PhysX titles?

Testing the impact of using a secondary RTX 5060 GPU to boost the performance of an RTX 5090 in PhysX games like classic Batman Arkham titles showed impressive results, with significant performance gains. PhysX, a physics engine SDK, was developed by NovodeX AG and later acquired by Ageia, which led to hardware-accelerated physics technology. While GPUs are better suited for PhysX calculations than CPUs, enabling GPU-accelerated PhysX can still cause performance hits. Utilizing a dual-GPU setup by dedicating the second GPU to PhysX processing can boost performance in PhysX games, as demonstrated in benchmarks with the RTX 5090 and RTX 5060.
