Some Games Run Better On Older GPUs Than On Nvidia’s New 50-Series Cards
In a Reddit post highlighted by The Verge, a user voiced concern over why PhysX was now disabled by default or ran on the CPU instead of the GPU, causing significant performance problems in games optimized for GPU-boosted PhysX. On Nvidia’s forum, the company acknowledged that PhysX has essentially been phased out because they will no longer support 32-bit CUDA applications for their 50-series graphics cards and future generations. Although the phaseout of 32-bit CUDA was briefly mentioned in a technical support article, Nvidia did not explicitly discuss the implications for PhysX or which games may be affected by the retirement of this technology.
