The A2A Simulations Community

First, I just want to say how amazing the accusim B-17 is...truly an immersive experience. I finally got it airborne last night...just amazing. I have the Orbx Australia scenary pack loaded with REX2 and it looked great. Which left me wistfully noting: the flight and all that leads to it is fantastic...incredibly realistic...but in the end, it is only about flying from point a to point b. Something is still missing. I kept wondering how FANTASTIC it would be if somehow the fidelity of the accusim pack and the amazing fidelity of the environment of FSX with its add ons, could be combined with a military simulation, such as the the B-172 Mighty Eighth simulation that came out years ago. To actually have to do mission planning, fly to the target battling flak and fighters, bomb accurately and get home again...all with your virtual squadron mates. Imagine a combination of FSX,accusim, environment add ons PLUS the aspects of a good combat simulation so a career could be built. How good would that be?? Sigh...that would be my wish...to combine the fidelity of the civilian simulation with a combat simulation. That is my dream for this sort of stuff. In the meantime, I think I read about a flak add on one can load into FXS to simulate a target? Anyone point me in the right direction? Have I got it wrong?

Secondly, just got a question: How to turn on the ground...not by the tailwheel or the rudder, I take it. I am using differential braking at present...is this right? Is this how you turn the B-17 on the ground?

Finally, seeking help: I seem to be having problems graphically with the sim in FSX. I have ATI crossfire Black Edition 5970s. It manifested itself like this: I'd be in the cockpit of the accusim B-17 starting engines...about 10-15 minutes in when suddenly, the screen would lock, start flashing (in a grpahical glitch sort of way) and the system would crash and reboot. This happened everytime. I reloaded everything, including the Orbx and REX2, and I also opened the Catalyst Control Centre and made sure the settings were checked for "application controlled". This seemed to work; but half an hour into the flgiht, the same thng happened again. I think it is definately a graphics problem; I also notice that when I hit Fly Now in FSX, just for a brief moment, the screen goes sort of black and glitchy, then immediately rights itself and goes into the flight. Hmmm.. Anyone else experiencing this? I am right, am I not, to make sure in FSX the Catalyst CCC is checked with application controilled? What about the Catalyst AI slider? Does this conflict with anything in the accusim pack or FSX that anyone knows of? I am also using the latest Catalyst drivers..10.6 I think they are. Any known issues with them? What drivers are others using for the accusim pack in FSX and who have a Catalyst card? Any advice at all would be much appreciated, since if this keeps going, clearly I cannot get much enjoyment out of the sim.

Thanks in advance.

Hi,

I have an ATI card aswell not come across that issue, I'm not sure but does FSX support crossfire?

I would check your power supply is sufficient. It sounds a little more than a setting is the issue.

As for the Flak, give this a whirl

Pittnuma, thanks for replying. Got the flak site...thanks. re the more substantive issue...hmmm..power you think. I will check that. IN the meantime, what Catalyst drivers are you using? I can't help but feel it is a driver issue for sure...maybe not graphics, but somewhere there is a driver problem. I also read a post in the avsim forums about some guy who had system crashes, the blue screen mentioning memory dumps, and ended up updating the driver for his internet router...turns out FSX speaks through the internet and Win 7 was not loading the right driver for it. Mt=y crash, when the screen freezes and goes into a flickering glitchy mess, is always accompanied by an irritating buzzing 'white noise'. I wonder if my on Creative XFi is clashing with the onboard sound chip...I need to check in BIOS if it has been disabled. Maybe that is it.

Anyone else got any idea? Freeze in game, blue screen talking about memory dump and then a system reboot. Accompanied by a 'white noise' buzzing. Ring any bells for anyone?

I'm using the 10.6's, seems OK to me. Using the force vsync mod which really helps with ATI, I have all my sliders set to max in CCC, I do not use app settings. Vsync is set to on unless app specifies otherwise, mipmap is high.

Can I suggest you read through this, it really helps and the advise is superb. For setting up FSX

ATI has always had a Shader issue with FSX but apart from that it's fine, smoke can slow mine down because of the Shader issue

Must admit I wish I had bought an Nvidia card this time (and this is from a Long Time ATI card user) Nvidia cards work so much better with FSX.

By the way mine is only a HD5770

PS what PSU do you have?

It also sounds like an over heat issue.

check the case, open it clean out the insides, remove any attached residue from the fan blades.
invest in a couple of larger case coolers. My case has a fan in the front that draws from the air slots in the front and blows into the case, and I have two fans in the back of the case that pull air out of the case and exhaust it into the room ...

The graphics with the b-17 are no doubt very intense. The card may be overheating.

FSX. don't like ATI crossfire, and you will have no benefit of it. (use only one cart for FSX) I found out the hard way))

About the driver I vent back to Catalyst 9.10, for my HD 5850

Make sure you are running DirectX Version 9.0c (may 2010) for FSX (NO DirectX 10) that gave me problems))

And of course you need FSX SP2 or FSX Acceleration (not both if you have the "Acceleration")

There was an issue for this with that sound card.It's quite a possibility as well.See the following thread.
viewtopic.php?f=29&t=21397

Also mos2net remembers the same thing about Crossfire and FSX that I do.It prefers a single graphics card or one that has just one graphics chip.I think it's the same way about nVidia cards as well,SLI will lower performance the same way crossfire will have lesser performance in FSX.
Here is a company that sells FSX computer systems and their component recommendation guide.

"FSX Performance Guide"

Warning
The Nvidia GeForce GTX 295 and ATI Radeon 5970 has
tested to be a significant performance inhibitor to FSX. This is
due to their integrated dual GPU design. Jetline is not offering
these models due to low FSX test results.


(as I can see you got two of them an that in ccrossfirer.)sorry))

To all who have replied...thank you. I note with surprise and alarm my crossfire 5970s are not much chop re FSX. That sucks...but hey, I gotta tell you framerates are not the issue for me. Getting the thing stable is the issue. I was very interested in the post about the sound card and its problems with accusim/FSX. My gut tells me that could well be the source of the problem...the white noise attached to each crash seems to suggest so. I'd like to test it: how do I sidable the creative sound card and use the on board sound chip? I notice in the device manager under computer that I have under the sound Tab: ATI high definition sound decice twice...then a "high definition sound device' and then the creative card device. Do I disable here all except the high definition sound device? And of course, make sure the speakers are plugged into the sound jacks on the mobo. Yes? Grateful any advice.

Great product, accusim! Can you the Lancaster next??? Pretty please!!!

To be honest, best way would be

to turn off pc
take the sound card out
power back on pc
uninstall sound card drivers (this will remove the correct items from device manager)
restart pc
boot to bios and re enable onboard sound


Just disabling is not the best way as remnants are still on the pc as I found out the hard way with an Asus sound card.

Try that.

Ok...as always, thank you for the advice people are giving. Still having problems with it crashing. This is what I'm going to do: I'm going to upgrade my soundcard; it's the only thing not updated for years. Too see if I can eliminate one cause of the problem with the crashing in the B-17 accusim package in FSX. Now, just to be sure....I hear there are issues with some Creative cards. Is that right? So...I intend to get the latest:X-fi Titanium Fatality Pro series card.

DOES ANYONE HAVE THIS CARD AND IF SO, IS IT OK WITH THE ACCUSIM B-17 PRODUCT AND FSX???

If I can kindly confirm that it IS ok, then I will upgrade to this with the latest drivers. Hopefully that will fix any sound issue. Gratfeul any views, comments, observations, advice.

Thank you in advance.

Am I reading your post correct? If you have removed the sound card, uninstalled drivers and fired up FSX and it is STILL doing it (even with on board disabled) then a new sound card even the latest version will not help it is something else.

Pitt

What power supply are you using?
Can I suggest memtest.

http://www.memtest.org/

Test the memory on board, take 1 slot out run FSX, does it still crash, if so replace the memory with the 1 taken out, does it still crash? Check your manual for the slot which must remain used when only using 1 stick of RAM, not sure on yours mine is slot 2.


What shows in the event viewer under critical? Anything to do with Kernel?
