Or at the least, it’s the most demanding ray tracing game you might actually play. Even with free frames, Portal RTX taxes the RTX 4080 much more than Cyberpunk 2077 does.Ĭyberpunk 2077 and Portal RTX couldn’t be more different (technically and thematically), but it’s a good illustration that Portal RTX might be the most demanding ray tracing game we’ve seen to this point. Portal RTX is a showcase for Nvidia’s next-gen graphics cards like the RTX 4090, and in particular, the unique frame-generation capabilities of these GPUs with DLSS 3. In both Cyberpunk 2077 and Portal RTX, I used the same DLSS mode and the highest ray tracing quality preset. For reference, you can see how the RTX 3070 held up with Nvidia’s Deep Learning Super Sampling (DLSS) set to Auto in Portal RTX below.

Even Metro Exodus Enhanced Edition, which uses full ray-traced global illumination, is leagues easier to run than Cyberpunk 2077.īut Portal RTX is even more taxing. Even two years after launch, Cyberpunk 2077 is the most demanding game in my GPU benchmark suite, both with ray tracing on and off. Portal RTX is way more demanding than you probably think. Ray tracing is taxing, but it’s how Portal RTX is leveraging ray tracing that makes it the next-gen benchmark I’ve been waiting for. Portal RTX is the most demanding game I’ve tested, and running it is only possible with clever image reconstruction techniques and the fastest GPUs on the market today.
