DLSS 3 - Frame Generation is Awesome

Hogwarts Legacy PC Performance Review & Settings Guide

DLSS Frame Generation is a great add-on for this CPU-limited game. 

If you have ready page 3 of this performance analysis, you will know that Hogwarts Legacy is very CPU-limited. As such, the prospect of DLSS Frame Generation will be music to the ears of anyone who has a high refresh rate gaming display. 

Strangely, we could not enable DLSS Frame Generation with Nvidia's DLAA (Deep Learning Anti-Aliasing) technology, which is a shame given how CPU performance limited this game can be with an RTX 4090. To enable DLSS Frame Generation, we needed to use DLSS Super Resolutionin quality mode, despite the fact that we did not need any performance gains from DLSS Super Resolution.

DLSS 3 in action

In Hogwarts Legacy, DLSS 3 does exactly what its supposed to do, act as a framerate doubler with AI generated frames that can dramatically impact Hogwarts Legacy's smoothness. With DLSS 3, we can bypass the CPU limitations of Hogwarts Legacy and keep this game at above 120 FPS at 4K Ultra settings at pretty much all times. That's great news for anyone who has a 4K 120Hz monitor or TV. 

As you can see, at 4K Hogwarts Legacy is entirely CPU limited with our RTX 4090 in our Hogsmeade test area, with DLSS 2 having no major performance impact. DLSS 3 and its AI generated frames changes that, giving us a smoother gameplay experience.

How are you able to measure fps? Are you using an external tool like Fraps?Quote

Great work on this, OC3D team. First game to see a real benefit of using DLSS3.Quote

Very good work. Very throughout and detailed.

It's nice to find a game that really pushes hardware.

I am interested to see if AMDs 3D cache CPUs will significantly benefit this game since they will be able to store far more data on die rather than constantly fetch from memory.Quote

From what I've read a fair few people even with a 4090 are still seeing GPU usage dipping down to 80% which means DLSS3 isn't working like it should.Quote
