Have you tried the full waterloo battle, how was fps there?
I honestly don't remember but it probably would not be very useful to quote a single figure of FPS for the full battle. Some areas have more troops, some have no fighting at different times, etc.
I have not had any laggy battles, if that helps. I fired up a sandbox the other day with the two allied armies V the french army. That was a bit jittery after they started manouvering, but hardly surprising with that many troops and all the settings on max. If I wanted to play a battle that big I would just lower my visibility distances, amount of veg, sprite ratio.
It's just 20+ fps isn't considered that good.
I doubt the reviewer known as total biscuit wil review it. But if i did, and 20+ is what je gets it would go like this:
I'm on a pc that has "lots of impressive hardware" and i get less then 30fps on full, that's not good enough in this day of age. Ect. Most gamers with a high end gaming pc, demands to play games on max with 60fps. They would say i can play witcher 3 or crysis 3 on max and have 80fps, yet this game bearly gices 30fps.
It would not help to say, you can lower the sprite ratio or view distance. They would expect any game be optimised well enough for them to play it on max.
Now from my understandig, this games runs mostly on the cpu, then ram and lastly gpu.
most other games run on gpu, then ram and cpu second, infact most expansive graphics showcase games use very little cpu (exception being gta v)
And since you have a modest cpu, but standard ram and good gpu, i assume the modest cpu is whats holding you back. So is perfectly possible those with i7 cpu's ect. will get close to 60fps on the same settings as you, in that case no problem, the question is, how much better would an i7 3770k 3.5ghz play then your i5?
I have that i7 and get less the 30fps in gettysburg just at the start of an army vs army sandbox game, even before anybody stars to move, with 1500 view distance on trees, objects and troopers.
But since waterloo is optimised, can i expect a 100%, 50% or just 20% increase in fps on avarage?
