TZeer Posted March 26, 2013 Posted March 26, 2013 (edited) Turning on the green floodlight in the cockpit causes a 30+ FPS loss. Here is the first screenshot. No floodlight. 110 FPS Second one, you can see the floodlight is starting to light up in the cockpit. Down to 91 FPS. And the third one, 78 FPS. I have done this test on both a 580 SLI setup and a GTX Titan. Both setups show the same behavior. I guess it's not a bug, but it would be nice if it would be possible to optimize it a bit. Specially for people who are already doing everything they can to stay above 30 FPS... Edited March 26, 2013 by TZeer

Sorin Posted March 26, 2013 Posted March 26, 2013 Similar to this but in outside view: try Ben's "benchmark" track on F5 camera and see what lots of light sources in the 3D scene do to your FPS... http://forums.eagle.ru/showthread.php?t=102857 I am not sure if this is a bug or it is normal.
Kameni Posted March 31, 2013 Posted March 31, 2013 If you have a pitch black screen - do you have frames "happening" - NO. So - the number of visible objects is smaler (pixels) to be rendered means less FPS, cause there are no Frames actually "happening". If you don't have lag when your FPS drop, then it's all fine. If you do - then you need more power in your PC :) (everyone does, it's never enough, thou)

I can turn on the light during daytime, and you can hardly see the light if you are not looking for it. But it still cut's off 30+ FPS. Turn off light, and FPS goes up again.

ENO Posted April 1, 2013 Posted April 1, 2013 I don't know the practicalities of it... but it seems that everything within your field of view in "the world" is being processed whether it's visible or not- hence why I can have smoke on the other side of a hill cripple frames every time I look in that direction (basically as soon as it enters the FOV). I'm not sure how it applies but FPS doesn't seem to matter about whether the item causing the issue is actually in view (though it would be in the field of view somewhere).

Kameni Posted April 1, 2013 Posted April 1, 2013 I don't know the practicalities of it... Sim does not know where you're gonna look next second :)
Kameni Posted April 1, 2013 Posted April 1, 2013 Wrong, if that was the case the FPS should be lower during daylight. And that's not the case. Yes it is, just maybe your PC is fit enough to cope with daylight. I can turn on the light during daytime, and you can hardly see the light if you are not looking for it. But it still cut's off 30+ FPS. Turn off light, and FPS goes up again. It is like the guy above me said - game processes everything.
_Dredd Posted April 1, 2013 Posted April 1, 2013 I noticed this too last night, but it seems to occur when the canopy was closed. Not sure if this might be an internal caopy reflection erature that was casuing it. Do you use HDR and can you test with canopy open and closed?

Will as soon as I get the time :) Yes it is, just maybe your PC is fit enough to cope with daylight If you have a pitch black screen - do you have frames "happening" - NO. So - the number of visible objects is smaler (pixels) to be rendered means less FPS, cause there are no Frames actually "happening". It doesn't matter if you are flying in day or night. The sim will crunch out as much FPS as possible unless you have vsync on. If you have less visible objects to deal with and less pixels, your FPS will go up as the GPU will have spare resources to use. If vsyn is enabled the FPS will stay at 60 FPS, and load on GPU will decrease instead. This post is was not about if the effect is there or not, or the computer is able to deal with it. It's about the possibility to get this optimized so we don't get this 30+ FPS loss by just switching on a light in the cockpit.
