Unfortunately this game requires a beefy system to run right and it has to be setup properly.
Its not the game per say, its the engine they chose. They should have went with the unreal engine which is way better optimized out of the gate compared to crysis. Crysis is just way to demanding of an engine.
They can do a few things to remedy this issue.
1: option to disable global shadows.
2: low texture options (something akin to wow, torchlight etc)
3: lower the amount of particle effects and movement.
4: Shadows on particle effects turned off.
5: Optimize pixel shaders or option to turn them off..
I guarantee shadows in this game are chewing up 20-30% of the cpu/gpu cycles. Just allow us to disable them for better gameplay. We asked for this 3 years ago in early access..
If they disabled or lowered the shaders to something we were using in dx9, this game would run way better. It should be an option.
Their netcode needs serious work. Opening an expedition portal shouldn't freeze up the game for any length of time.
Higher some better coders to tweak and optimize the engine or flat out begin porting the entire game to another lesser demanding engine.
Realistic graphics look sweet.. The game looks amazing but its way too demanding on hardware. I hope they weren't planning on releasing this on consoles, it will burn out ps4/xbox consoles so fast it won't even be funny.
