AMD réfute les rapports de Ryzen 7000 Incohérences de performances entre les fenêtres 11 et Windows 10
The statement from AMD on the matter follows.
We have been made aware of reports of unexpected performance deltas in certain games with AMD Ryzen desktop processors as well as performance variances between Windows 11 et Windows 10 in certain game titles. We are currently investigating but based on testing to date have not observed a material difference in game performance between OS versions across a variety of operating scenarios and game titles.
Many factors affect gaming performance, including the game engine, CPU architecture, GPU selection and memory choices. As new architectures enter the market, we often observe performance anomalies which must be addressed by the component vendor or the game publisher. This is not a new phenomenon nor is it unexpected.
As we have done since the introduction of Ryzen, when these performance anomalies are brought to light we will use them to steer our partner engagements with game developers and ecosystem hardware partners to implement optimizations that eliminate the variations.
