50系显卡光追单元是不是比要40系更稳定(或者换个说法，更平稳些？)

不，50系的纯光追性能相比40系是倒车的，皮衣黄打算搞t模型预测光追路径的技术路线
...

怎么来的这说法？

所有其他游戏和程序都无法重现这种倒退，这种情况应该首先怀疑这个特例吧。

tom也测了这个项目，他们的判断是
“One final ray tracing benchmark we have is the 3DMark DXR Feature Test, where we report the average FPS rather than the calculated score. This is similar to full RT in a game, only done via a standalone benchmark and perhaps in a more vendor agnostic fashion. The RTX 5090 worked in this test, but it was slower than the 4090. Clearly, either some driver tuning or an application update are in order.”
