Intel recently released fresh driver for their discrete Arc graphics cards. And one of its features revealed a curious detail.
The driver now has the ability to disable Advanced Performance Optimizations (APO). This is a special feature that optimizes the performance of the adapter to improve its performance in benchmarks. And tests have shown that sometimes the increase due to this function is very large.
For example, in 3DMark TimeSpy, the Arc A380 card with APO disabled scores 4449 points, and with it already enabled 5241 points! True, in the Port Royal test, the difference between the results is only 4%, that is, apparently, APO affects the performance of ray tracing very little.
It’s not yet clear how much of an APO impact in games, but now it’s clear why Intel Arc graphics cards perform so much better than their competitors in 3DMark than they do in games.
