Having to design with game lag is kinda disappointing. It’s supposed to simulate space warfare, not “how much lag can this computer handle”. Anyways, are 50 km/s+ railguns realistic in real life? How about sub-gram projectiles?

How about sub-gram projectiles? Railguns are meant to shoot light projectiles with hyper velocity. It has so many strong points: Easier to hit, longer to shoot, softer to resist. US Army once studied about hand held infantry railgun, with 0.1g projectile at 16km/s muzzle velocity: Recoil was no higher than puny handgun, 1.6kg*m/s. More extreme cases are not that feasible on Earth because of atmosphere, totally fine at space. Theoretical muzzle velocity in space is beyond my knowledge, however 50km/s seems moderate. If you mind the rail integrity, coilgun can be an alternative.

Qswitched has some infolinks in the game that discuss this. A key point AFAIKT is that armor behaves very differently when struck by something going faster than the speed of sound in that material (which for most armors is impractically fast for atmospheric projectiles - 2 Km/s at least). At that speed I think essentially the material can't transfer forces within itself and is resisting the impact with sheer momentum; "strength" of material is almost irrelevant. Thus Whipple shields...
The Mythbusters had a great episode where they tested how much water was required to block bullets. Small caliber low velocity handgun rounds penetrated 1-2m; high velocity 50 caliber rounds shattered on impact with the waters' surface and sprayed a fountain of water everywhere.

Would it be feasible then to make my ship out of layers and layers of nothing but whipple shields, spall layers, and graphite gel?

Composite armor is a science, you random mix of materials is rather sub-par, stuffed whipple shields with inner bulkheads and spall liners are better, I can get 5g @5km/2 in ten megawatts of power and 1-2 tons of mass, at max RoF
My coilguns can throw 5kg rounds at nearly 10km/s and will shread 19cm of Beta Titanium, much stronger then A-Carbon, they also fire 5 rounds per a second

Could you please paste a design example of both an armor layout, and that rather sweet-sounding coilgun?

Who needs to state power requirements? With the right capacitor, you can fire your gun on watts of power once every few weeks!

And then the UNSC has such a hard time fighting the Covenant in-universe...

Even assuming 50% efficiency, that's only 2.5 GW draw. More concerning is the cost of what must be 5 kg of expensive magnetic metal glass every shot.
