Very. Although I must admit, after gaming at 1440p for the past month, it really isn't that terrible anymore thanks to DLAA. 1440p with anything else whether it's FXAA, SMAA, and especially TAA (🤮) just looks so disgustingly blurry/jagged. Still, more pixels is more pixels and can't go wrong with that.
 
The new version of DLSS5 (3.9.16) that dropped today gave me a 10FPS boost to my base frame rate in cyberpunk at 4k. So up to 60FPS if you are using 6x frame gen. I'm using 2x frame gen so I got a 20FPS boost overall. Pretty happy with that. I'm still using preset B for DLSS because it looks much better than preset C in Cyberpunk and preset C has some micro stutters on my system while preset B is flawless. Preset C does perform about 10FPS better than preset B though.

About the performance update using less resources with the new version.

“A new version of DLSS 5 on NBA 2K27was just released, and modders have already extracted it and are running it on unsupported games. Modders are comparing performance between the older and newer Neural Rendering (NR) model and found it up to 40% faster than the previous one.

Official DLSS 5 running on unsupported games delivers up to 90% better performance than the leaked version — Nvidia says the new NR model uses 20% less VRAM and processes neural workloads up to 2x faster
​

Nvidia's new Neural Rendering model is smaller but better.”

In this video, Hardware Unboxed tests Nvidia's new DLSS 5 neural rendering model (released in October), which claims to run twice as fast as the original version while reducing VRAM usage by 20% (0:00 - 0:30). The host evaluates these performance claims using NBA 2K27 across the full GeForce RTX 50 series GPU lineup.

Key takeaways:

• Performance Gains: The new model delivers significant speed improvements—averaging about 83% faster at 4K and 94% faster at 1440p across the RTX 50 series (9:42 - 10:06).
• Usability: While the performance hit is still substantial compared to disabling the feature entirely, the new model makes DLSS 5 much more viable for mid-range cards like the RTX 5070 and RTX 5060 at 1440p (12:42 - 13:04).
• Visual Quality: The host finds that image quality remains largely unchanged and that the original visual artifacts—such as lighting flicker, inconsistent skin tones, and halo effects—persist in the updated model (14:30 - 16:59).
• Conclusion: While the October update is a necessary step in the right direction, the technology still requires further optimization in both performance and visual stability before it can be recommended for widespread, everyday use (18:10 - 18:48).”

The new model definitely runs twice as fast, but your actual performance gain will depend. Here's an example using CP2077 at 1440p.

OLD Model (Preset A):

NEW Model (Preset B):

1792448765849.png


So using the old model, my fps in CP2077 is 78 which is a render time of 12.8ms. Out of that 12.8ms, 3.6ms was used for NR at 1440p resolution. The new model runs twice as fast so instead of a 3.6ms render cost, that is now just 1.8ms. 12.8 - 1.8 = 11ms is now the total render time with the faster model and so the new fps should be 91, and it is so the math completely checks out. In this scenario though, the new model only translates to an actual performance gain of just 16% over the old model, but the gains at 4K will be far more significant. Power consumption did drop by 21 watts at 1440p so there's probably an even bigger power savings at 4K.

“NVIDIA's Faster DLSS 5 Model Gets Pulled From NBA 2K27, Modders Report Up to 90% Gains​

by DrUsmanSaleem Today, 20:25 Discuss (4 Comments)
NVIDIA shipped its faster DLSS 5 Neural Rendering model with NBA 2K27 on October 16, and it didn't take modders long to pull it out and test it elsewhere. Renan Maniero on X extracted the new 310.9.16.0 build of the DLL. That lets people inject it into games that don't officially support DLSS 5 through tools like RenoDX and OptiScaler. The new DLL also keeps the older model around as Preset A, with the new one sitting under Preset B, so comparing the two is as simple as switching presets. Gaming Optimized on X did exactly that, and found the new model running up to 90% faster than the old one in The Witcher 3. The channel points out that the gain varies from game to game, so 90% looks like the best case rather than the norm.

That roughly aligns with NVIDIA's own claims. The company says the October update shrinks the model by 24% to roughly 118 million parameters, cuts VRAM use at 4K by 20%, and runs the neural rendering workload up to 2x faster than the September version. NVIDIA also quoted up to 40% higher frame rates in NBA 2K27 specifically. Officially, DLSS 5 is still limited to RTX 50-series GPUs and GeForce NOW. NVIDIA plans to bring it to the RTX 40-series, though there's no date yet, and there's no word on RTX 30 or RTX 20 support. Modders, apparently, aren't waiting, since the OptiScaler README notes a modified runtime that gets it running on RTX 20-series cards as well.“
 
I'm not going to make claims about general operation across all brands of cards but for me. My power usage was around 590 to 614 watts. With the latest driver from Nvidia it dropped to 590 to 605. With the latest update to DLSS 5 it's now sitting at 565 watts all the time. This is in Cyberpunk at 4k with Reno DX DLSS 5 profile 1. DLSS 4.5 Ray reconstruction profile F and DLSS profile C with path tracing, Ultra plus, HDR and about 430 mods with an overclocked card and no under volt. I can't imagine a game that can push the system harder than this. I would say the power usage is no longer being pushed past the safety limits even under the harshest conditions, for me at least.
