PhysX performance

We paired an RTX 5090 with an RTX 5060 to test PhysX performance in legacy titles—and found that dual GPUs still deliver measurable gains in specific scenarios, but at a premium that only hardcore enthusiasts and PhysX collectors should consider. If you’re chasing raw rasterization performance or play modern AAA games, a single RTX 5090 crushes this setup; if you’re running a PhysX-heavy library and have the power budget and cooling, the secondary GPU can push 15–40% gains depending on the title.
