Nvidia's RTX 5090 still can't game in 4K without DLSS 4
That's where DLSS 4 comes in. With the latest iteration of Nvidia's frame generation technology, you'll be able to game in 4K with frame rates over 200 fps. Of course, you're relying on software performance to generate all of those additional frames rather than pure silicon, and not all games offer DLSS 4 support.
