How to optimize ray tracing performance in games?

Yeah, ray tracing can be a beast to tame—especially when you're chasing that smooth 60fps+ in demanding games like Cyberpunk 2077 or Alan Wake 2. I had a similar struggle last year with my RTX 3070 build. First thing I tried was comparing it to my old GTX 1080 Ti setup—big difference, no surprise. But the real turning point came when I switched from forcing high settings to *intelligent scaling*. Instead of lowering shadow resolution across the board, I treated dynamic resolution scaling (DRS) like a dial: GPU-bound? Crank it up. CPU struggling? Back it off. Games like Metro Exodus Enhanced Edition handled it beautifully—input lag stayed low, and the visual drop was barely noticeable on a 1440p monitor. Now, when it comes to TAA vs. TAAU—those are the secret weapons. TAAU (Temporal Anti-Aliasing Upscaling) is like DRS’ sharp-eyed cousin. I ran a side-by-side with Forza Horizon 5: TAAU at 90% render scale gave me near-native quality with way less noise vs. plain TAA at 100%. Plus, newer engines like Unreal Engine 5's Lumen integration play really nice with it—less flicker, smoother global illumination. Just watch out for the ghosting in fast motion; dialing Light Temporal Weight in NVIDIA Reflex settings helped a ton without ruining RT clarity.
