Awesome indeed...

Are you trying to say it's actually AWESOME WEDNESDAY?!! NICE!!!! I don't care about regular update Tuesday anymore!

It's clearly not Tuesday anymore...

Would love to have EDGE support SLI. I have 2 GTX 480's that are begging to be fully utilized.

I had the same problem this morning. I could not log into the multi-player servers, but I could log in here and on the website. Hmmm...

Yep. Same here. Was looking to buy Combined Arms, but it is not in the E-shop.

Nice Shahdoh!! You know I'm always ready to give it a test run!!

Would those who join be spectators, or in cockpit? If in cockpit, what module(s) will you be using? Thanks.

Good explanation Shahdoh. Just keep in mind Topcat that it is a piston engine and not a jet engine. The throttle is exactly that in this case, throttling the intake of the engine, depriving it of what it needs to perform. The RPM setting is a desired setting for the engine/prop to spin, being a constant speed prop. So, if you want to achieve a certain prop speed, you have to open the throttle enough to achieve it. Once that point is reached, the prop pitch changes (prop angle of attack increases) so as not to go past the desired prop speed. As the angle of attack increases, you're pushing more air and developing more thrust. But again, it is a piston engine, and like your car, you don't want to rev too high for too long, otherwise you overheat and destroy your engine.

Rock, thanks for making your work available to the community. Really good stuff...

Sounds to me like some corrupted files within the DCS World install on your box. I know it's a last resort option, but uninstall DCS World and reinstall. It's not the P-51 module. I use it almost daily for hours at a time with no crashes (at the fault of the module :)). Are you overclocking your PC at all? Could contribute to an issue. My OC would crash at just about the 1 hour mark, usually when I was on my final approach for the evening. Anyway, some ideas to consider...

I only see it when I am taxiing to the runway in 1.2.2.7570.

Really nice. Especially the polished metal behind the 'Twilight' lettering.

Yeah, no problem weaving in and out of buildings, harassing the local populace, but as soon as I pull the trigger at low altitudes...slide show.

I have run into something similar with P-51D. I also own both P-51D and BS2. Frame rates are good in P-51D, until I my strafing run gets to about 300 feet above the ground. Then...slide show. Pulling out of my dive, guns still firing, leveling off. I get it that there is a heavy demand for number crunching at this point, but doing the same thing in BS2 does not lead to the same drop in FPS. My computer specs are in my signature below. Is the drop in FPS due to GPU or CPU?

There's a no-HUD view? :smilewink:

Winz has the process right. I have the same install. All the upgrade module does differently than the full version is check for an existing BS1 Serial Number in the registry.

"The feeling of being there, well, just isn't there." :huh: ????? I'm on the other end of this experience. I get totally immersed in flying it, especially low altitude, between buildings, under bridges, tight corners around hills... Shadows rolling through the cockpit, monitoring coolant temperature, airspeed, aiming for that perfectly smooth landing... TrackIR does help a lot though.

I would love to see more Developer Notes like this thread started with. I was asking a few questions about Manifold Pressure vs Engine Speed and I think an article about it in this thread would be really useful. Yo-yo and a few others chimed in and were very helpful in pointing out that the propeller changes pitch (and therefore pushes more air) to maintain engine speed. Would be great to see a full write up on the topic. Other ideas might be to talk about limitations of the P-51D, what to avoid, and what to take advantage of. I've been watching some of the Dogfights series on YouTube where they interview actual P-51D pilots. They talk about special maneuvers like 'pull the stick into your gut, give full bottom rudder, then push the stick forward to recover'. Discussion on this kind of stuff would be great too. I really enjoy listening to these guys talk about how they actually flew the aircraft beyond what the Army gave direction to. Talking about this stuff might be useful for Yo-yo too so he can improve his sim design in case we discover something that you can do in the sim that would be impossible in real life.

It might be your graphics card. I have run my AMD 1090T at its native 3.2GHz and it does pretty well. I don't realize too much of a difference when I overclock all 6 cores to 3.825GHz. However, I did notice a difference in performance when I upgraded from a Radeon 5750 to a GeForce GTX480. Clock speed of your CPU comes more into play when you have a lot of other units flying around, or are playing a sim like A-10C where there are a lot of other aircraft systems operating together. BTW, I'm totally into P-51D as well. I'm enjoying watching all the YouTube videos on the P-51, then going to the sim and trying to copy what is talked about.

That makes sense. So is it fair to say that as good as the Merlin engine was, it was not able to take full advantage of what the propeller was capable of, even at 1400+ HP? If so, engineers must have been constantly trying to balance engine power with propeller design.

Not sure why you seem to be so personally offended.

If you uninstall BS1, won't it take the BS1 Serial Number with it? If it does, what will the BS2 Upgrade use to to verify you have a BS1 install? Eh, whatever. The point is, you will be able to use the BS2 Upgrade in DCS World without launching Steam if you do it the way you described.

You won't ever be able to uninstall BS1, but you will be able to run BS2 in DCS World without having to launch Steam.

I'm having trouble understanding how additional manifold pressure, past what is needed to maintain a 3000rpm prop speed, affects speed. If the propeller produces thrust, it makes sense that the faster the prop spins, the more thrust is produced. So, for a constant speed propeller, it would take a certain manifold pressure to achieve that maximum prop speed at a given altitude. However, If I'm flying at 2000ft, my prop speed is 3000rpm, and my manifold pressure is 46in HG, why would I need to increase to 61in HG? Or, even further, why would I need WEP? I have done experiments in the sim where my airspeed is ~250mph with ~45in HG of manifold pressure. My prop speed is 3000rpm. Then I increase manifold pressure to 61in HG and I begin to accelerate. WHY?!? My prop speed has stayed the same at 3000rpm. Similar situation during take off. Why do I accelerate faster down the runway at a higher manifold pressure even though my prop speed is the same (3000rpm)? Thanks.
