smink1701 Posted January 31, 2014 Posted January 31, 2014 Thanks team. As much as I would like to see major new elements added each week I appreciate that you don't serve things up until they are ready. And that the overall project seems to be on schedule. Thank you!
Burning_Bridges Posted January 31, 2014 Posted January 31, 2014 If cold air is denser, wouldn't it also increase drag?
falstaff Posted January 31, 2014 Posted January 31, 2014 Freycinet said: For true flight simmers this was a very good update I agree, but can you please stop these side-swipes/put-downs at those who may have been less than bowled over...? (...what is an *untrue* flight simmer? A *flight-liar*? ) 1
DD_bongodriver Posted January 31, 2014 Posted January 31, 2014 If cold air is denser, wouldn't it also increase drag? yes it does is the short answer.
SCG_Neun Posted January 31, 2014 Posted January 31, 2014 Looking good guys.. I agree totally with Freycinet as well. Patiently watching this sim unfold and loving the results.
JtD Posted January 31, 2014 Posted January 31, 2014 (edited) If cold air is denser, wouldn't it also increase drag? Yes, it would. If the engine developed the same power, you'd achieve a higher indicated air speed but a lower true air speed. With your engine creating more power, you'll end up with a similar true air speed, but a considerably higher indicated air speed. In a simple estimate a temperature drop of 10% absolute (like -15°C instead of +15°C) will give you 10% higher density, which will give you 10% more drag at the same true speed but also give you 10% more power. You should see an about 5% difference on your speed indicator. The effect on climb rate, however, will be a lot bigger. Edited January 31, 2014 by JtD
=IRFC=SmokinHole Posted January 31, 2014 Posted January 31, 2014 The effect of temperature on performance isn't minor or academic--it's HUGE. On a hot summer day my initial climb rate is about 2500 FPM. I don't fly much in the winter but I had to recently to test after some maintenance. At 5•C I was averaging somewhere around 3000-3500 FPM. Cold air does help overcome the lack of density at higher altitudes but the influence is not as great. You can be at ISA -40C at sea level but climb up to 20000 and the seasonal temperature differences are more minor, say ISA to ISA - 15C.
6BLBird-Dog Posted January 31, 2014 Posted January 31, 2014 Looking good Cooler Air has increased density and as such tends to have increased moisture content which improves atomisation ,(the attachment of fuel particles to air particles ). With the additional density & moisture combustion pressure increases slightly and when ignition happens from the spark in a petrol engine the resulting rapid burn is far more even and efficient .The draw back when the engine is cold is the need to increate fuel to air ratio to start up and gradually reduce it until the optimal engine operating temperature is reached . With Compression ignition Engines the diesel fuel may solidify in extreme cold and requires either additive or warming to liquefy .A heater may be used in the air intake ,combustion cylinder or both to warm the air prior to starting the engine promoting detonation on injection and many pumps also have a cold start button that will briefly give extra fuel for the injectors at the initial crank up which will briefly increase pressure over normal cold engine compression values .
JG4_Sputnik Posted January 31, 2014 Posted January 31, 2014 good news, thank you. and now I'd like to test the Il2
sallee Posted January 31, 2014 Posted January 31, 2014 If this experience doesn't teach me anything else, it has really put into context the massive amount of work that goes into each little step forward. Rather like RoF, you can almost sense the sweat and tears each week! I'm not one to expect an aircraft a week in any case, but it's a real insight. Thanks devs!
Allons Posted January 31, 2014 Posted January 31, 2014 Hello everyone. It's +28 C and a light midday rain on the Caribbean isles. Aaaah, i knew there was good contact to Luthier - best greetings
YoYo Posted January 31, 2014 Posted January 31, 2014 FM looks better now. I agree too, but dont like this new "motion blur" from cocpit and outside.
sturmkraehe Posted January 31, 2014 Posted January 31, 2014 The trails look nice. It would be even nicer if the development of trails depend on external conditions. Depending on external condition the trail length could change or there could be no trail at all.
Dooga Posted January 31, 2014 Posted January 31, 2014 So are we now allowed to make our own graphic settings decisions again? Or at least turn &%!?# SSAO off? (sorry for the negativity, but I'm simply not seeing myself shell out 400 bucks for a new GPU just because of this...)
Veteran66 Posted January 31, 2014 Posted January 31, 2014 the radio spotter work fine but it is to quietly Where is the new spotter mission? stalingrad air and ground mission
Bulkhead Posted January 31, 2014 Posted January 31, 2014 Cool, fly high this weekend I watched a show about fighter training and some of the f-16 pilots that was transferred to alaska from more southern bases said the fighters preformed better in sharp turns because of the cold air. The engine got little more power too. They said the air is like metal, it expands in warm and shrink in cold. Takeoff roll was shorter in alaska than california.
ST_ami7b5 Posted January 31, 2014 Posted January 31, 2014 FM looks better now. I agree too, but dont like this new "motion blur" from cocpit and outside. as I wrote in F5 thread: "The disturbing thing (for me) is that the blur effect is active also when changing FOV (zoom in/out) and when looking around with trackir... I try to focus my eyes when looking around. I like the new Stalingrad map - buildings (remains) are no longer only black & white".
DD_bongodriver Posted January 31, 2014 Posted January 31, 2014 still not fixed the nose bounce/wobble thing, what is the deal with the view always returning to centre? when did that happen?
EAF_Paf Posted January 31, 2014 Posted January 31, 2014 what is the deal with the view always returning to centre? when did that happen? What do you mean by this?
Jaws2002 Posted January 31, 2014 Posted January 31, 2014 (edited) Some more .../... and can't get rid of. Motion Blur. At this point I'm not even surprised anymore. Edited January 31, 2014 by Rama
DD_bongodriver Posted January 31, 2014 Posted January 31, 2014 I am not using TrackIR since mine broke, so I was using mouselook, before the viepoint would stay where I put it but now it keeps self centering to the forward view

(sorry for the negativity, but I'm simply not seeing myself shell out 400 bucks for a new GPU just because of this...) I have to agree with you, ROF allows us to shut this off. Why are we being ignored, this sim is unplayable with the graphics the way they are.
=38=Tatarenko Posted January 31, 2014 Posted January 31, 2014 I am not using TrackIR since mine broke, so I was using mouselook, before the viepoint would stay where I put it but now it keeps self centering to the forward view There are four view options that can be cycled by pressing F9.

Why are we being ignored, this sim is unplayable with the graphics the way they are. Nope, it's not. Just finished flying couple of missions. Point is, it's not unplayable for all, seems that most of us can play. It is unfortunate that some are having so seriuos problems with it, but I am sure it will get fixed.
dburne Posted January 31, 2014 Posted January 31, 2014 The gauges are all out of focus/blurry now when I switch views and go back to cockpit view, momentarily. I am still having severe stuttering/framerate issues when strafing ground targets and fps set to unlimited. This on balanced preset. Dead Zones still resetting to 0 between each session ( closing and opening of the program). 1
1CGS LukeFF Posted January 31, 2014 1CGS Posted January 31, 2014 hmmm.... and ... how do I know the engine temperature in Bf when the thermometer is not working? Does it really have to be explained again why some things are incomplete right now? 2
kendo Posted January 31, 2014 Posted January 31, 2014 (edited) Stalingrad has lost the monochromatic look it had which I think is an improvement. Though it's a little difficult to be sure because things are out of focus a lot of the time from the (truly God awful!) motion blur effect. Really, who thought this was a good idea? It's even triggered from the cinematic effect movement on external view F2. And as already mentioned instruments are blurred when you adjust your view. Not a good idea to inflict this on us when there is NO way to turn it off. Sorry to be so critical, but it is really annoying!! Edited January 31, 2014 by kendo 1

Yeah noticed it when doing my strafing run but the stuttering/low fps made it hard to tell which was which...
sallee Posted January 31, 2014 Posted January 31, 2014 Some more .../... and can't get rid of. Motion Blur. At this point I'm not even surprised anymore. No great fan of that myself. Still, if it took a week to add it, perhaps it will take a week to get rid. I thought I'd had too much gin (as if that's possible).
caryatid23 Posted January 31, 2014 Posted January 31, 2014 Hi! I'd like to throw in my lot for the anti-motion blur crowd. I've a good rig and it does not hurt my performance I just cannot stand it. Motion blur immediately takes me out of the action and destroys the suspension of disbelief. There I am with the full sensation of flight, turn my head slowly, and I'm back in my office looking at a blurry monitor. I'm sure other folks have different opinions and those are totally valid. Things like SSAO and Motion blur ( also shadows and reflections ) are the reason for graphics settings. I am ok, with the graphics profile idea in general, but there certainly need to be some options that are toggle-able regardless of graphics profile. Hopefully that will be the case by release time. Thanks
No601_Prangster Posted January 31, 2014 Posted January 31, 2014 Stalingrad looks really realistic now with better colours and more detail. The 109 cockpit has been repainted with much better weathering and I'm not having a problem with the motion blur. My 770 card runs Ultra High settings at a consistent 60fps (Vsync). Nice work!
Jaws2002 Posted January 31, 2014 Posted January 31, 2014 Motion blur can be turned off: Options - Camera - Cinematic camera = Off 2
kendo Posted January 31, 2014 Posted January 31, 2014 (edited) Had another flight and I agree Stalingrad is looking incredible now. Have more buildings been added now as well or is it just the colours that have been changed? Whatever, the effect now is extremely realistic. The artillery shelling seems to be heavier now too. The landscape generally is looking better than ever, but flying low over Stalingrad and looking back over the length of the city with shells exploding on land and in the frozen river and the palls of black smoke - WOW!! Good work. (Just make the blur optional please - without me having to turn off the cinematic effect - which I like!) Edited January 31, 2014 by kendo
caryatid23 Posted January 31, 2014 Posted January 31, 2014 @Jaws. Thanks! I had not seen that. It is nothing concrete but the sim feels very very good right now. I'm loving the lagg.
