I’ve seen many instances of some software having DRM that significantly degrades the performance of the software, or worse, the performance of the entire OS due to heavy background tasks. Prime examples include Denuvo and all those Adobe background processes. Why can’t they just simply use the TPM or the other 5 security chips embedded into the CPU so that they don’t bloat the system?
Denuvo is a cache defeat mechanism. Of course it kills performance. If CPUs still worked like 386s and 68000s, having eight copies of every function and bouncing merrily between them would make no difference. But modern processors are only fast because they spend negligible time waiting for RAM to get its act together. Every squandered microsecond is a thousand cycles burned.
