This will allow you to run GP3 on Windows 10 (and perhaps Windows 7) without needing to dual boot Windows XP, or using a very old computer. Follow this guide ONLY if you have major FPS issues when running in Hardware Mode. You will still need a high-end graphics card to achieve acceptable FPS. My 1GB Radeon HD5870 gives 25fps at all times, except at the start of races and from the back of the grid, where it can drop as low as 14fps, but usually stays around 20-21fps. If your card is less powerful than this, expect lower FPS still. [u]Instructions[/u] 1. Install GP3 as normal, update to GP3 1.13 and put the NOCD patch into the GP3 folder. Downloads here: http://www.grandprixgames.org/read.php?50,699633 2. Download the latest version of dgvoodoo2 (as of June 2016, it's v2.52) http://dege.freeweb.hu/ 3. Copy dgvoodoosetup.exe into your main GP3 folder (the same as where the GP3.exe is stored). 4. Then, from the dgvoodoo zip, also copy the three DLL files which are in the MS folder into the GP3 folder. These will be labelled DDraw.dll, D3D8.dll and D3DImm.dll 5. Run dgvoodoosetup.exe from within the GP3 folder. Go to the DirectX tab, make sure the following settings are in place: Videocard: dgvoodoo Virtual 3D Accelerator Card VRAM: 1024MB 6. Make sure the following checkboxes are ticked: No mipmapping; Fast video memory access; Application controlled fullscreen/windowed state 7. Uncheck anything I haven't mentioned. You may now close the dgvoodoosetup program, it does not need to run anymore. 8. If you get a blank screen when you load GP3, right click on the EXE and set the Compatibility Mode to Windows XP (Service Pack 3) 9. Once loaded, you should be able to set the resolution within GP3 to 1280x1024 if you have a very fast, modern computer. If the FPS is too low, reduce the resolution lower to suit. I have a computer that was average/fast in 2009 and it struggles above 1024x768. The first corner is especially slow FPS if I'm at the back of the grid, after that it's fine. Perhaps someone with a faster PC can verify whether they have any better performance. Remember dgvoodoo2 is a DirectX wrapper/emulator and the reason this game is slow out of the box on Windows 10 is because DirectX7 apps are not supported natively anymore. [u]Notes[/u] For even higher performance, try the following: 1. Go into Catalyst Control Centre or the nVidia Control Panel and make sure all AA and AF settings are set to OFF 2. Set Mipmap level and Texture Filtering to "High Performance" if on ATI, or look for similar settings in nVidia Control Panel 3. Try the 4GB Patch! http://www.ntcore.com/4gb_patch.php Cheershttps://www.grandprixgames.org/read.php?1,1097753,1097753#msg-1097753Sun, 19 Apr 2026 16:11:11 +0200 Phorum 5.3-dev https://www.grandprixgames.org/read.php?1,1097753,1171057#msg-1171057 https://www.grandprixgames.org/read.php?1,1097753,1171057#msg-1171057[mediafire]]]> mikanhassaku Grand Prix 3Mon, 13 May 2024 19:13:41 +0200 https://www.grandprixgames.org/read.php?1,1097753,1171013#msg-1171013 https://www.grandprixgames.org/read.php?1,1097753,1171013#msg-1171013 alvaro_degas Grand Prix 3Sun, 12 May 2024 19:32:07 +0200 https://www.grandprixgames.org/read.php?1,1097753,1170882#msg-1170882 https://www.grandprixgames.org/read.php?1,1097753,1170882#msg-1170882However, it is very troublesome as it is not possible to convert Jam files all at once.

firstly mind to keep mirror details without the "as forward view". Keep it to "None", since that eats so much in PO required.

but if you use dgvoodoo exporting (is the better solution) , and leave in 512 (it's already oversampled in 1024x768 ) and check how is going if it's playble (PO).
if you want put it at 1024x768 (but mirrors still to "None") and check again, but anyway notthing over 1024x768 has sense.

You may also go in the
"C:\GP3\Utility\dgVoodoo" and dgVoodooSetup check the settings for the folder c:\GP3 and check to disable apply phong option or linear filter or nomipmap activating.

With dgvoodoo only, it's visually correct, but very slow. (it's ok in 512 with no details, but very slow in 1280 with all details, as the PO in the second pictures shows)
Same as what I got with my default install.



With DxWnd, I get the same exact result I get with my default install. (transparency issues and PO is about the same)

[www.grandprixgames.org]

So, unzip the folder "gp3" in c:\ (mind just this path needed to be c:\ ).

then go in the created folder c:\gp3 and find out the subfolder "GP3++" and drag on desktop.
then follow these steps (we will try 1988, cause tyrrel black/transparency more evidence):
In the subfolder you have brought in desktop...

1. doubleclick on 00a BASE DGVOODOO ONLY and answer in the terminal with "88" and then "Enter" key.
2. doubleclick 01 Fisica and open in C:\GP3\Carsets\fisica the file " fisica_1988.g3p ". the click on "Update gp3" to export the physyc.
3. doubleclick on 02 Carset (that is gp3Edit) then open from C:\GP3\Carsets the file "GP3 1988Carset.GP3" and export into game.

So, Now, just click on "03 GP3++" (it's gpxPatch icon), and so click on "Avvia GpX" button...

After the intro, go directly into a quick race , and set by internal/external cameras the tyrrell 017 of Palmer. see if all ok (should be with dgvoodoo). Then, increase the resolution in game to 1024x768 and check again (and PO).

So, after, do the same steps above, but :
1. replace with double click on "00a BASE" instead dgvoodoo only. and then... step 2,3.
but last step double click on "03b GP3++ DxWnd" and start the launcher from dxWnd.

That should be already in 1024x768. so, just check the tyrrell again.

Do the test in both pc with nvida and ATI and Intel card.

- PO is almost twice as high, so I get way over 100% in the first bend.
- some parts are not drawn on the wheel at the very beginning, plus text on the LCD display of the wheel is very ugly, really, pixellated.

I also tried the same setup on my ATI card (RX5700) which has transparency issues. (see [www.grandprixgames.org])
The result with dxwnd + dgvoodoo is even worse than dgvoodoo only: even the sky is white. But at least, performance is ok, though there is an effect on PO. (doubled from 40 to 80%)

Thanks for your answer. I did some more tests and indeed, the Nvidia GPU is never used. I ran GP3 on both laptops, after setting the performance option both in nvidia drivers and in windows Display settings. (I can't disable the Intel GPU in the bios.)
To make sure I had no interference with other apps, I launched GP3 alone, without Wheeler (displays the steering wheel controls) or OBS.

The values in the resouce monitor were clear: the NVidia GPU is never used. The Intel one is, with a load around 30% on both laptops. So I guess last time, it was OBS and Wheeler which put some load on the NVidia GPU.
One weird thing with GPU Load. I set the performance (NVidia) by default, and while I could see Nvidia GPU load peaks when starting dwnd and gpxpatch, as soon as GP3 starts, if falls to 0. Meaning the game forces the intel card when it starts. The Nvidia GPU can 't be selected in GP3, I see the Intel one twice, even after making a performance test.
One other games, the NVidia GPU get a very high load immediately.

It's interesting what you say about nvidia, because I have a lot more bugs with the desktop GTX1050 than with the intel integrated. I'm wondering if Nvidia has the same drivers issue you mentionned, I should maybe try to get older drivers ?

I'd like to keep OBS, i'm recording the game and integrating Wheeler in the video to show pedals and wheel position.

That laptop is a Dell 7720SE, and it has a Core I7 3630QM, with a dual HD4000/GT650M (Optimus) as graphic cards. The game runs smoothly (with a few transparency glitches), I never reach 100% occupancy, even in rain when starting a race, so I figured I shouldn't have issues running the game on newer hardware.
Boy was I wrong !

We have another "old" laptop, an HP Envy, equipped with a Core I7-4702MQ and a HD4000/GT750M duo in it (Optimus again). On the paper, it's equivalent. In real life, definitely not. The PO is twice as high, and I can't figure out why ? The CPU should run faster overall (and is clocked higher so should also be faster on a single thread), the graphic card is supposed to be faster also. But I reach 170% PO in the first bend when starting a race.

So I tried to find another solution, and used an old desktop computer (core i5-6600 + Intel G650), with the same install / dxwnd config). Like the second laptop, PO is too high to be usable. The visual glitches are the same as with my laptops, so I'm starting to think that I'm not using the GeForce, always the intel integrated GPU. (despite asking the opposite in the drivers)
Is there a way to check which GPU GP3 is using ? When I look at the resource monitor, both GPUs are working, but load is low (around 30%).

I borrowed a GTX1050 to make some tests and plugged it on that desktop computer. I get more glitches (wheels half drawn, many parts of the cars not displayed, holes in the cockpit). But PO drops and there are no more slowdowns.
I ran the game with dgvoodoo instead. No graphic glitch, but higher PO.
Weirdly, i'm unable to run the game in a window with dgvoodoo, which has two consequences:
- when switching from menu to race and back, sometimes the game resolution is wrong (far too small, and not centered on my screen)
- i can't record the game anymore, it's not visible by OBS, even in "full screen" mode.

I tried to run dgvoodoo and dxwnd at the same time, by launching the game with dxwnd with the dgvoodoo dlls installed. The game won't start.
I saw that dxwnd has a folder to put alternate dlls, typically to use dgvoodoo as a renderer, but I can't make it work. The files don't seem to be taken into accound. Anyone could help me on this ? Is there an option to enable ?

I use the last nvidia drivers, should i try older ones ?

I tried all I could. I have even reinstalled Win 11. In the end, I worked around it by using DxWnd with dgVoodoo 2.

I can't believe... it was working three days ago. A simple GP3 + dgVoodoo 2 setup was rendering a perfect racing game at a perfect speed. And all that in a Windows 11 Pro ARM64 VM on Parallels Desktop v17. Now it just refuses to work.

Meanwhile other old games with the same age like CS 1.6 and Max Payne 1 just works flawlessly.

I'm about to bang my head into the wall...]]> Castello Grand Prix 3Wed, 25 May 2022 04:42:03 +0200 https://www.grandprixgames.org/read.php?1,1097753,1158730#msg-1158730 https://www.grandprixgames.org/read.php?1,1097753,1158730#msg-1158730
Here I'm not using dvdoo (yet).

But my GP3 doesn't start after a fresh reboot.

I have to kill the GP3.exe proccess and start it again. Furthermore, this happens just once each reboot.]]> alvaro_degas Grand Prix 3Tue, 24 May 2022 11:46:02 +0200 https://www.grandprixgames.org/read.php?1,1097753,1158729#msg-1158729 https://www.grandprixgames.org/read.php?1,1097753,1158729#msg-1158729 zifox Grand Prix 3Tue, 24 May 2022 11:10:52 +0200
