I can see that only the DLSS option is unlocked but there is no increase in performance.
If you are able to enable the DLSS option in your graphics card settings but are not seeing any improvement in performance, there could be a few potential reasons for this.
One possibility is that DLSS may not be fully supported in the games you are playing. While DLSS is supported by a growing number of games, it is not supported by all games, and the level of support can vary between titles. It is important to check if the game you are playing has full DLSS support, as this may affect the extent to which DLSS can improve performance.
Another possibility is that DLSS may not be fully optimized for your particular hardware configuration. DLSS relies on the use of Tensor Cores, which are specialized hardware units designed to accelerate AI and deep learning workloads. If your graphics card does not have Tensor Cores or if the Tensor Cores are not being utilized effectively, you may not see the full benefits of DLSS.
Finally, it is also possible that DLSS may not be the most suitable solution for improving performance in your particular system. There are other factors that can affect performance, such as the overall system configuration, the game settings, and the workload of the graphics card. It may be necessary to consider other solutions, such as adjusting the game settings or upgrading hardware, to fully optimize performance.
