How does metro exodus enhanced Edition run a lot better than the standard game

It doesn't make sense at all

They removed all the baked lighting, DLSS 2 helps, and all the RT lighting uses a propagation system that takes a few frames to fully fill where only the first bounce is calculated in real time.

So that explains why the fps on the standard game is 40 to 60 and the enhanced edition runs at 70 to 90 fps at 4K max settings DLSS on quality mode and RT on max settings

Since this version calculates a lot more things in real time that have proper 3D acceleration, it relies on the CPU a lot less, the original game had a huge problem with performance but on the CPU even if your CPU was very good.

Despite being more advanced and needing ray tracing as the bare minimum, because the CPU had much less game and rendering elements to calculate, it is a more optimized version.

A good example is scene mirror reflections vs ray traced reflections. metro exodus doesn't use scene mirror but it is an example. scene mirror has to duplicate the geometry and lighting and all, meaning a lot more draw calls for the CPU and low performance no matter what, while ray traced reflections searches infos about the color of the pixel at the end of the traced ray, which is theory would be much more expensive, but because we have hardware acceleration on the GPU, it actually offloads the work of the CPU and uses the GPU to accelerate it.

And since the GPU load is much easier to scale than the CPU load, you can have much better performance this way, even if your GPU isn't very good.

Best example of this problem is the first Crysis (original), it uses scene mirror reflections for ocean meaning even with the best GPU in the world, you'll never get good performance at max settings because it puts a lot of stress on the CPU. among other things lol

So what I am trying to say, and I have been saying this for a decade despite many people calling me crazy (honestly no offense but mostly ignorant people), the most important part of a gaming PC isn't the GPU, it's the CPU, and especially single thread performance.

A very good CPU with strong single core performance will ensure even unoptimized games will run well, and will ensure that you will suffer lag spikes the less, because the 1% performance (a metric more important than average framerate) will stay high.

If your GPU isn't very good, you have plenty of options especially now with DLSS, etc... however if your CPU isn't very good and the game isn't well optimized, there is nothing you can do about it.

No, I would say that is a vast oversimplification. The answer mostly is "it depends"

So metro exodus enhanced Edition is cpu bound I mean that might explain why upgrading my cpu from a i9 9900ks to a ryzen 9 5950x gave me 2x the performance

and why does metro exodus enhanced Edition only use 800MB to 1.3GB of ram I have 64GB of ram but it isn't using it

Think you might be looking in the wrong place for RAM usage

DLSS allowed me to ultra everything at 1440p with ULTRA ray tracing at 70-110 FPS. The game performance was incredible, I love a developer that loves their product and perfects it.

Metro: Exodus Enhanced Edition is an example of a remaster done right. Not only it looks far more superior to an original game in every single aspect, but it also runs and performs a whole lot better. I enjoyed the hell out of it with my RTX 3080 card. Gotta be the best looking RTX title up to date. The lighting is just unspeakably good in this one.
