This week Hitman 3 was updated on PC to receive RayTracing technology, and maybe that didn’t bode well to come out with rescaling technologies Nvidia DLSS and AMD FSR 1.0, and the reason is more than obvious: the game improves visually, but the stress it generates on the system is so exaggerated that the game with RayTracing in Ultra Quality, and at an HD resolution of 3840 x 2160 pixels, moves at 30 FPS with an Intel Core i9-10900K alongside an Nvidia GeForce RTX 3090.
If you want to improve performance in Hitman 3, you can remove shadows by RayTracing (RT), but the performance improvement is minimal, which drives it up at 36FPSwith regard to the 108 FPS which achieved without RT. Hence the need to use resizing technologies in a mandatory way to try to play at higher resolutions with greater fluidity. Moreover, it is even recommended, since it is indicated that at long distance the shadows are better seen with the RT deactivated.
“RT shadows have less of an impact on game visuals. They improve the quality of sun shadows in the usual way you’d expect, adding twilight for nice smoothing, even when applying it to vegetation , which isn’t necessarily that’s true, as that’s expensive and complex on its own. They also introduce very tight contact shadows to emphasize detail, which is good. However, RT shadows also have a limited range: beyond a certain distance, RT shadows fade and we see shadow maps instead, and unfortunately these shadow maps have no type of filter and are quite coarse.”
“RT Reflections are relatively very heavy on the GPU, to the point that an RTX 3090 running low settings at 4K sees 60% less performance at low, 67% worse at medium, and a noticeable 72 dropping from near 4K 120fps to under 60fps all the time is a tall order and as you’ll see in the video on this page, less capable cards at lower resolutions still have a mountain to climb in terms of decent performance, while the gap between AMD and Nvidia hardware varies based on Charge RT.
Ultimately, for AMD RDNA2 GPUs, I would only recommend setting reflections to low for RX 6800 XT GPUs and above…but even then, that decision is questionable, as the performance drop is still severe , while FSR 1.0 does not. do a pretty good job of resizing to compensate and there is no option to use FSR 2.0, at least for now. Really, I imagine most Radeon users will opt for the RT shadows, which are much more cost effective on these GPUs.
For Nvidia users, I recommend that only RTX 3080 level GPUs choose to use RT reflections set to medium, while RTX 3070 level GPUs choose low reflections. Anything below this performance class is not functional, and I would suggest using only the RT shadows option. By the way, based on IO Interactive’s recommendation on specs, I would only suggest using reflections in conjunction with DLSS; yes, the impact is really that high.”
