Massive FPS increase with Resolution decrese (?)

[Shadylurker]

I was just curious why this is, I know in theory why, But is it known why this makes such a massive difference in this game?


EDIT: Whoa quick update i didnt enjoy playing windowed with 1024x768 so i changed the ini to almost full screen window, my fps full screen were 20 over water. with the only thing changed was window mode im over 100fps now in the same spot!

EDIT 2: Problem is fixed by forcing my GPU to max clocks. Game would not make my GPU move from it's idle clocks (300/300mhz) Now that my GPU runs at max clocks (925/1125) all the time the game runs great.

no multi thread support, overload for GPU, lot of possibilities...

That does look suspicious - I remember when the only way to run Il-2 in Win 7 Beta was to run it in windowed mode (with the window equal to the screen res).

Well, if you go from a resolution of 1920x1080 to 1600x900, you get 70% of the pixels you had originally. If you go down to 1280x720, you get only 44% of the pixels you had originally. The graphics card has to render all the pixels... if it has less than half of them, at least creating the image and sending it to the screen should be around twice as fast.

Of course there's all the computation that you need to do either way, but I think post processing effects are applied to every single pixel. Anti-aliasing and pixel shaders are some examples. The less pixels you have, the faster it goes.

Correct me if I'm wrong though.

I don't get why so many people complain. I don't think I've ever played a game with AA on, or pixel shaders on max. Or over 1280x720 for that matter. It's not that bad. People are complaining about not being able to have AAx8 or whatever it is, heh.

Modern games run on my rig at 5760x1080 with graphics on high and 4x anti-aliasing, 8x anisotropic filtering around 60fps no problems. Cliffs of Dover should be no exception. FSX, A10, Wings of Prey, Rise of Flight all run at that res with ZERO problems.

I noticed this too....

I can triple my FPS from FLL screen 1920x1080 to windowed 1280x720...


I understand the gain, by less pixel, but it should not be that much..

in DCS A-10C you gain 15% max by doing such a thing...

How do you set res for window?

On the serious side: if you haven't really played a game with AA, I strongly suggest you do, as it makes A LOT of difference.

And people are not complaining about not being able to have AAx8. People are complaining about not getting a playable FPS on high end rigs. That is a big difference.

just alt tab, and resize the window with your mouse !

I tried running COD at 1024x768. Looks and playes amazing. Too bad I need a microfying glass to see whats happening.
