You'll never be able to run it.
Crysis Remastered key art

Crytek just announced that they are remastering the first-person system killer called Crysis. Crysis Remastered is in development and is set to be made available this Summer for the PC, Xbox One, PlayStation 4, and the Nintendo Switch. The Switch? Yes, the Switch. Crysis is coming to the Nintendo Switch.

Joining Crytek on the development of this game is none other than Saber Interactive. Saber Interactive has developed and co-developed a number of titles over the years such as World War Z, Vampyr for the Nintendo Switch, and The Witcher 3 for the Switch. Crysis Remastered will include the same gameplay as the original but with "remastered graphics and optimizations for the latest modern hardware."

I take that to mean the game will run better on multi-core CPUs than the vanilla game does.

Those graphical upgrades will include things like better textures, better art assets, temporal anti-aliasing, SSDO, SVOGI (voxel-based global illumination), state-of-the-art depth fields, new light settings, motion blur, parallax occlusion mapping, and particle effects. There will also be new additions like volumetric fog and light shafts. Also included are software-based ray tracing and screen space reflections.

In November 2019, Crytek released a demo for their software-based ray tracing. You can download that demo for yourself right now. It may give you a good idea as to what sort of performance you might be able to expect. There will be a performance cost for those that use ray tracing, moreso for those that don't have specialized hardware for ray tracing.

Besides those improvements, it sounds like it will be the same game you played before. The game that is great, up until the point the aliens show up.

The original Crysis arms players with the powerful Nanosuit on the battleground of a new war against alien invaders. The Nanosuit’s speed, strength, armor and cloaking allow creative solutions for every fight, with a huge arsenal of modular weaponry to give you incredible control over your play style. Become invisible to stalk enemy patrols, boost your strength to lay waste to vehicles, and deflect damage to dominate your enemies in this enormous sandbox world.
