## DLSS 4.5 Under Scrutiny: Performance Drop for Older GPUs Early user feedback from DLSS 4.5 testing highlights a performance reduction exceeding 20% compared to version 4.0 on RTX 20 and 30 series graphics cards. This data appears to align with previous communications from Nvidia, which had anticipated possible negative impacts on older GPUs. DLSS (Deep Learning Super Sampling) is a proprietary upscaling technology from Nvidia that uses artificial intelligence to increase game resolution while improving performance. New versions of DLSS are often optimized for the latest GPU architectures, which can lead to decreased performance on older cards. It will be interesting to assess whether future software updates can mitigate this issue. ## Implications for Gamers These results suggest that owners of RTX 20 and 30 series cards may not fully benefit from the improvements offered by DLSS 4.5, or even experience a performance degradation in some scenarios. It is advisable to carefully monitor performance after the update and consider whether maintaining the previous version of DLSS may be a more advantageous choice.
