I've never come across this particular problem before.

First, make sure to have applied the patch and display driver update. Also use my CA.INI fix.

Run in Software mode first (if you are trying to use 3DFX mode and a glide wrapper.

You could also try disabling one core on your processor.

Two things. What is the CA.ini fix and where to get it?
I tried Software mode with no luck, not any of the other modes either. Also have no idea of how to disable one of my cores.

The CA.INI fix. Just replace the file in the game install folder...

Use WinLauncherXP to disable processor cores easily...

I too am having the stutter problem 10 seconds into flight in 3dfx mode.I have done everything listed to setup the LB2.I did install it on XP,copy it over to my W7 x64 system patched up and run all the utilities.Im using DGvoodoo.I agree its a sound looping problem or something.How do we fix this because frame rate makes the sim impossible to fly at like 2-4fps.Its running fine in d3d but of course the graphics in d3d suck bad compared to 3dfx.

My system,

AMD 9850 Quad
6GB ram
W 7 x64
Nvidia GTS 250 1GB ram
DVDRW

akwar - your guess is as good as mine nowadays. It's good to hear that it runs OK in D3D though.

akwar - I almost forgot about Phoenix's fixes. Go to down to Phoenix's LB2 Final Solutions towards the bottom of the page linked below. Read the description there and see if you think it would help.

I personally haven't got round to testing it myself yet, so can't vouch for it. I'd love to know how you get on if you do use it.

I am happy to report that fix worked perfectly and the sim now runs in 3dfx with only one issue so far.I had one screen freeze on starting a mission.Rebooting sim and flew 2 missions in the campaign with no issues.Ahhh a classic is brought back to life,thanks.

I'm glad it worked for you on first trial, akwar. It would be more interesting to know if it would do, say, 6 or 8 missions in a row though.

Thanks for testing it!

I was able to get through 8 missions without issues.

Congratulations! That's really good to know. Thanks for the further testing.

Glad you got it to work =)

Edit:
A few important things of note that I probably should have included in the readme:

* The fix already contains a line to set processor affinity to a single core. Setting affinity manually via Task manager or another 3rd party utility could cause unexpected behavior

* The fix contains a memory lie just like G+'s old one. There shouldn't be any need to limit memory manually, and I recommend you don't as this has the potential to cause problems.

* VERY IMPORTANT: If I understand what this line in CA.ini does, then I think it's pretty important that you have it:

[Backdoors]
HEAP_PERCENT=0

Do NOT use the EmulateHeap WAC fix unless you know you need it. This was included in G+'s oldest database. Microsoft's impelmentation of this seems to be broken on all 64-bit Windows OS's I've tested it on, causing more problems then it solved.

* Last thing:
I don't want to go through anymore troubleshooting rounds, but if you have any of the following problems then I should be able to fix them with minimal effort as I have a good idea of what my resolve them:
- Sound loops
- Windows Key, Alt-tabbing causes crash
- Database doesn't agree with 32-bit OS's or XP

thank y'all for the tips. I've fixed my problem through your opinions.

especially, thanks to Flyboy & Positiveg

I'm really enjoy my Ah64 flying

**p.s

for those people who got " wrapdll.dle " error, try this :

Hi alphapass - thanks for that 'wrapdll.dle' fix suggestion.

Hi Phoneix:

Thanks for your ACT file. I was using PositiveGs-database file vut switched to yours to give it a try. I have no difference on any of the files, both run great for me.

However, it seems (so far) your dgVoodoo settings are working better for me. In the past LB2 ocasionally stopped responding when exiting the game (no big deal since I already was exiting) but now it hasn't done it yet (I had only tried like 5 or 6 times so far without it happening)....

Hello,

This is the first post I make on this forum, although I have been lurking around here for a few years in search of knowledge and tips & tricks.

I thought I'd share with you my recent experiences with Longbow 2 and how I got it working beautifully and in my opinion better than ever.

Longbow 2 has been with me for almost half my life now (I'm 28). Having played it on and off whenever I have had the chance and my computer setups allowed it.

Earlier this year I bought a new Macbook Pro laptop and on it I installed Windows 7 (64 bit) alongside OS X to be able to run Flight Simulator X and use my 40" LED TV as a display. And be able to sit comfortably in my armchair. :-)
Then I thought of the idea to try this out with Longbow 2.

After some initial struggles with the installation I found the Vista/Windows 7 package here and finally, success. Thanks Flyboy!

For stability I applied the LB2 compatibility database.

I have tried both nGlide 0.96 and dgVoodoo 1.5 extensively and dgVoodoo seems to be the better working of the two. Way better control over results than nGlide.

Having a laptop brings some nice benefits to the table. Windows give you different configurable power saving plans. Among the options are mininum/maximum allowed CPU power. I simply set the values ridiculously low (like 1%/2%) and now LB2 runs absolutely perfectly. The flight model feels like I remembered on my earliest systems. No more sudden blade stalls or things like that. HE rockets are more accurate aswell but not quite perfect. Limiting the CPU also got me rid of the repeating of input glitch that some people are experiencing.

As I mentioned I use my LED TV as a display and i set the resolution and refresh rate in Windows to 1920x1080@24Hz. This in combination with vsync in dgVoodoo also keeps frames down and more like the speeds we were used to back in the day.

All in all this masterpiece now runs smooth as silk on a larger display than I ever had before.
Back in 1997 I had neither of X45 joysticks, 40" TV:s or comfortable armchairs... :-D

I hope Combat Helo will match this! ;-)

Hi phuse!

Wow that's quite a story you wrote there. It's good that you finally decided to join, and I thought it only fitting that I should reply, at least first, as you directly thank me!

Thanks for typing the results from your observations, there's still something for all of us to learn as we keep progressing with trying to get LB2 to run on more and more modern and awkward systems. I for one never knew you could limit your available CPU power through power-saving options on a laptop, and I have a Windows 7 32-bit laptop.

It sounds great that you have a comfy armchair and a 40" TV, LB2 must look really cool on that!

And all on a Mac!

One question: Which LB2 compatibility database did you use?

Regards,
Flyboy

Flyboy:
I used Phoenix's final solution (LB2_fix.zip) found on your site.

Thanks for letting me know, it might come in useful to know in the future.

phuse - one more thing I meant to ask, what CPU do you have - you know, how many cores and what speed?

Flyboy: It is a Macbook Pro with Intel Core i5 2.54Ghz, 2 cores, 4 GB RAM, GeForce GT 330M.
