I'm getting better performance with DLSS 4.5 than with DLSS 4.0
As crazy as it sounds, I've been experiencing this across several games. I'm not complaining, but I assumed I'd get lower performance since the newer version should theoretically be more demanding.
I have a laptop with a 65W RTX 3050 (6GB VRAM), which is currently bottlenecked by a single 8GB stick of RAM. I recently got curious about trying the latest version of DLSS, so I used DLSS Swapper to update the DLSS version in Doom Eternal. When I played with it set to "Balanced" mode, my performance was actually higher and much more stable. It peaked at 140 to 160 FPS in certain situations, and my average was around 120 FPS.
On the other hand, with DLSS 4.0, it maxed out at 120 FPS. While it stayed above 100 FPS most of the time, I kept getting frame drops down to 80 FPS.I've also noticed this performance boost in other games like Dead Space and Dying Light The Beast.
Does anyone know why this is happening? I'm really new to all of this, so I apologize if it's a dumb question. Also, sorry if this post is a bit confusing—I'm using Gemini to translate it because my English isn't the best.
