AMD, NVIDIA’s graphics card drivers seem to have a lot of bugs recently, for example, NVIDIA because of the Nvidia Display Container Service caused the CPU occupancy more than 10% higher than normal, which led to system lag.
Google software engineer @Osvaldo Doederlein has just discovered that AMD Radeon RX 7900 XTX cards lose nearly half of their scores when using the latest version of 3DMark for Time Spy testing.
UL / 3DMark developers have confirmed that about 3% of users may currently be affected by the issue, but the company was unable to reproduce the problem internally. AMD appears to have internally reproduced the issue, which is presumably a driver issue, so now affected gamers will have to “roll back to a previous version or wait for a future driver fix”.
3DMark officially also gave an example, as shown in the figure below. From the results, the Ryzen 9 5900X with RX 7900 XTX can run 24587 points under the old version of the driver, but only 12861 points after the upgraded driver, which is nearly 48% less.

Of course, the 3DMark running score bug does not seem to be a common problem at present, and most players will not run smoothly, so it does not need to be too urgently fixed for the time being, but it is definitely something that Radeon users should pay attention to.
