Grand Prix 2 + VDMSound + Dual Core CPU [fixed]

I've been Googling a while and I haven't found anything related to my problem and I believe that I'm not the only one.

I have just upgraded my PC and my new processor is Intel Core2 Duo. My old processor was Intel Celeron D and I played GP2 under Windows XP with VDMSound 2.0.4 and it was running quite fine. Now it doesn't work anymore. I get either a black screen (with "Try to limit CPU usage"-option under VDMSound's Performance tab). "Cap DOS Timer Frequency" is not good option either. With none options selected from Performance Tab, game runs too fast in the beginning and I can't hear sound at all. (Now I've installed VDMSound 2.1.0.)

I continued Googling and found something about problems related to Tomb Raider I and it was adviced to set processor affinity only for CPU0 for ntvdm.exe. So I did it, but it had no effect on GP2.

Without VDMSound GP2 is playable and speed is normal, but sound stutters like before, so is there any way to get GP2 running properly with Dual Core and VDMsound? I have tried DOSBox and GP2 runs well with it, expect I have to reduce in-game resolution to VGA. That will be my last option if there is no way to go for VDMSound again.

Thanks.

I have this problem also but then with gp4, gp4 works great but the sound stutters

OK, let's wait for other replies.

Which sound card are you using?

I have Sound Blaster X-Fi and had strange crackles in the GP4 sounds some months ago. I fixed it by installing original drivers from the driver CD.

You can also try disabling either hardware/software acceleration from the sound options if you already haven't.

Problem :
After installing GP2 and vdmsound
the game work but it runs stuttering or with stuttering sound.

Possible solution :
Start the setup.exe (with vdmsound) and check the sound settings.
Vdmsound doesn't work perfect with Soundblaster Pro or Soundblaster 16/AWE 32.
Choose Soundblaster. Not Pro or 16/AWE 32.
Don't use the sound test button ! The Program could crash when you use the Sound Test.
Save the configuration.

Very strange, because I had already chosen Sound Blaster when I still had my old processor, So I thought your suggestion won't work.

Still I decided to run Setup.exe once more and I checked my configuration. I changed IRQ from 5 to 7...

Then I launched the game and it works!

Thank you very much, and for all the others: check that IRQ-setting, if you have problems running GP2 with your Dual Core-machines.

Anybody managed to get a newer wheel going with gp2?
I can run it, but dont want to play on keyboard.

I guess you mean USB-wheel?

In that case it's probably not possible to get all the functions of the wheel working. I'm using an USB gamepad and I have got it to work with GP2 by configuring keystrokes with bundled profiler software. I'm using Logitech Profiler and it can't launch profiles automatically for DOS-games, so GP2-profile must be activated everytime before launching the game.

There is also a tab for game controller emulation in VDMSound, but I have never tested it. I don't know does it work, but you can try.

Oh wow the Logitech profiler works with gp2? never even thought of it.
I have a momo force so I will give that a shot with the profiler when I get a chance.

I had tried the emulator with VDMSound before and it wouldnt work. It works perfectly now, you do need to scale up otherwise there isn't enough travel to be able to setup a wheel. How did you get the keystrokes picked up in game? i tried to set them up but it wouldnt detect them, wow if I can get that working Gp2 can easily be played, cant wait!

Configuring keystrokes works exactly like it does with Windows-games. First, you'll have to setup GP2 to use keyboard in the game and you will get the following controls:

A=accelerate
Z=brake
,=left
.=right

...and so on.

Now go back to profiler and begin, for example with right paddle. Now, go normally to the screen where you can add keystrokes and record "A" and type "accelerate", etc. Now go through all the keys you need and of course, you can keep the game manual close, so you don't need to launch game every time to check up how did it go.

I don't know how you should scale the wheel, because I have never played GP2 with a wheel. For my gamepad (Logitech Rumblepad II) sticks, everything works fine without doing anything extra.

When all is set, launch GP2 profile manually and enter the game. Now everything should work fine, expect if you need extra tuning for the wheel.

Check that you have the same IRQ-setting in GP2 setup and VDMSound. 7 works fine for me.

It still can be too fast. Sometimes rebooting computer or restarting the game should work. If there's a sure way, I'd like to know it, too.

The game works good with dosbox via D-Fend Reloaded on my PC. But not with gp2lap.

If you have a modern fast computer, and Vista, you can forget vdmsound or dosbox.
I play GP2 under win98 in a virtual PC. (Microsoft Virtual PC 2007)


Windows Vista Home + Virtual PC-Konsole (Microsoft Virtual PC 2007) +Windows98 + GP2 + gp2lap

And now you can capture the GP2 window with a software like CamStudio.
