Odd FPS Value

[Devrim]

This is my observation. It may be wrong. I'll try to tell with my poor English.

 

In first image, you see an A-10C with 60 FPS.

 

 

In second image, we're under the ground and seeing A-10C and the sea with 60 FPS.

 

 

Now, we're under the sea and again with 60 FPS.

 

 

Here're the questions. Isn't FPS suppose to go down in second image? Also, isn't it suppose to go down futher in third image? ... at least a few frames?... no difference?...

 

In my opinion, the FPS values must be different. Because "on the ground" camera doesn't see the sea. So, if "on the ground" and "under the ground" FPS values are equal, then I'm thinking that DCS always calculating sea movements (motions).

 

And if so, isn't there a mistake here?

 

Thank you.

I think this has long been a "problem" with lockon (and other games) and is one of the reasons players always ran with the sea a low quality, as it is rendered under the terrain.

 

But, you may actually see a difference if you turn Vsync off. You have a good PC, so your not actually seeing what your FPS limits are in those screen shots as Vsync is cutting in a limiting your FPS to your monitors refresh rate (60hz).

 

Turn Vsync off and let us know what happens.

 

I'd be interested to know anyway.

Thank you really very much for your interesting.

 

As you said I turned VSync off and tried again.

 

Cam on ground: avr. 74~76 FPS,

Cam under ground: avr. 64~67 FPS,

Cam under sea: avr. 95~101 FPS.

 

I'm really confused now. :) What do you think about these result?

Makes perfect sense

 

first option is just what your normally getting in game

second one is rendering water as far as you can see, hence a decent hit in frames

third you don't see any water, nor ground textures, hence far less stuff to render, and thus higher fps then in 1.

 

Nothing odd there.

Oh, yes, actually it seems right there, I don't know how I didn't see it... May be, it was early morning, my head didn't work I think...

 

Yes, as you said, those values shows that DCS doesn't calculate (render) the sea when cam is on the ground...

 

Thanks. :D

 

Case closed!
