I don't think it's just "turning on" ray tracing, since AMD often do ok when just using ray traced shadows. In "lightly" ray traced titles like Metro, they can deliver 3070/2080 Ti level performance. The issue issue is that performance tanks as more ray tracing effects are added. Cyberpunk is basically a worst case because it has RT reflections + shadows + GI + diffuse lighting.
the biggest issue seems to be the BVH, open world games run really badly on AMD, see the example of Watch Dogs, which only uses RT reflections...
an open world game has a very dynamic and unforeseeable amount of dynamic objects coming in and out of range...
I think that's what mainly tanks AMD cards. they perform reasonably well with Quake 2 RTX I think, and that game is 100% RT with every possible RT effect used... but it has a very manageable BVH structure I assume due to being relatively tightly confined spaces with not much going on inside them either
