Recently, PC gamers were surprised to discover that NVIDIA quietly dropped support for 32-bit PhysX on RTX 50 graphics cards. This led to a massive performance drop in older games.
The creator of the VerbalSilence YouTube channel decided to clearly demonstrate how the gaming experience deteriorates when PhysX comes into play. He played on a PC equipped with a GeForce RTX 5080.
For example, in Mirror's Edge, one could get 250–600 FPS, but as soon as glass is shattered — the frame rate drops to 7–30 FPS.
In Borderlands 2, shooting at water can cut the frame rate in half, from ~120+ FPS down to 50–60.
