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?

Tom's Hardware tested classic Batman Arkham games with an RTX 5090 rendering and an RTX 5060 dedicated to PhysX.

Using NVIDIA Control Panel settings to offload PhysX to the second GPU produced noticeable performance gains.

The results suggest older PhysX-heavy PC games can still benefit from a dual-GPU setup.

This is especially relevant after RTX 50-series changes impacted support for 32-bit PhysX.
