Some other 2D games may also require the Direct Draw hardware to be disabled. As mentioned below in the subspace fix;

Install the 2.77 drivers and the latest version of Direct X. Using DirectControl right click the icon it creates in your system tray. Now, go up to Direct Draw. Choose DISABLE.

The most common slowdown in a Direct 3D game is caused by mipmaps. Disabling them is very simple.

See this picture (the Carmageddon 2 picture) to possibly help you tweak Nv3tweak for a game yourself.

If this DOES speed things up a lot, let me know the game name and any other values you may have changed.

This game runs slow on almost every system. DO NOT use -highres, it will run very bad.

To reduce MAJOR hard drive thrashing from Windows 95, edit the shortcut for Carmageddon. Right click on it, Goto Properties, click the MEMORY tab. Under MS-DOS protected-mode (DPMI) memory type: 32768

To correct the slow speeds make sure your card is set up according to my Riva Tweak Guide. Then go to your display properties (right click desktop, go to properties) and choose the Riva 128 tab. Make your settings look like this picture.

To correct the 'disco lighting' install the 2.77 drivers, available in the Riva Tweak Guide.

You should set up your card's Riva 128 tab (see above) to the same picture.

From the game's directory, run Ddconfig.exe and choose Advanced Properties. Make sure it is set to use your Riva 128 (primary display) and check the Disable Mipmapping box.

From the game, click the Graphics settings (the eyeballs) from options. Play with the gamma untill it is an acceptable level.

You should set up your card's Riva 128 tab (see above) to the same picture.

To fix the movie problem uninstall all CODECs you have. This will most likely fix it. To uninstall CODECs, enter Control Panel (Start Menu/settings/Control Panel) and choose Multimedia. Choose the Advanced Tab. Now, click on Video Compression Codecs. You can now click on them individually and choose Properties, followed by Remove.

If you haven't done it yet, you must install the Riva patch for it to work correctly.

If you have weird backgrounds, go to your Riva 128 Tab in display properties (Nv3Tweak), Change USE SQUARE TEXTURES ONLY.

For the game crashing, try FIRST setting up your swap file as normal (as compared to fixed size). If you're using the Yamaha MIDI try setting your sound card to NOT USE FULL DUPLEX and this may fix it. Also make SURE you're using the nVidia 2.0 reference drivers. You can get them from my Riva Tweak section.

Go HERE for my Riva setup/tweak guide. Make sure you're using low quality sounds to avoid hard drive thrashing.

To bring up the brightness go to the IdGamma homepage and download the newest version. It works great with this game.

Make sure you have the 2.0 drivers or newer. This is pretty much a must. You should set visual quality all the way up and resolution to 640x480 or 800x600. This game really runs good on Riva 128 too.

If performance is low, try disabling Mipmaps in Nv3tweak.

Finally a FINAL patch game out.

Download the patch here.

Go to the Nv3tweak control panel applet. (Go to Control Panel, then Nv3tweak). If you don't have it, you can grab it over at the files section.

Start MotoRacer 2 in nVidia (Direct 3D) mode.

If it goes too slow, exit the game, switch your desktop to 640x480. Restart the game. If it still runs too slow hit ALT-ENTER to switch to an almost-full-screen window. Now it should be fast!

If you bought this game you were probably stunned to find out it had no support for Direct 3D (I know I was!).

You can't tweak it too much, but here's a couple ways that help a little bit. First of all, to make sure you're not having too much hard drive access read my hard drive tweak guide.

Set your display colors to 16 Bit (I noticed a slight performance increase).

Unload all other programs (I highly recommend this for all games).

Go HERE for my Riva setup/tweak guide. This will help you get the colors right.

For more tweaking head over to 3 Finger's site.

This game only supports Glide, which even on my Voodoo2 runs bad. This game is beyond tweaking. In fact, it's a crappy game anyway.

The only way to improve speed is to lower image quality. Since this game already has very poor image quality it will look even worse! You're better off just buying a new game. =)

software

(direct draw)

Install the 2.77 drivers and the latest version of Direct X. Using DirectControl right click the icon it creates in your system tray. Now, go up to Direct Draw. Choose DISABLE. Start the game and it should be much better. To see framerates, hit ESC then F.

Mine jumped from a jerky 15 fps WAY up to 95 fps.

This game tweaks the exact same as Jet Moto;

Make sure you have the 2.0 drivers or newer. This is pretty much a must. You should set visual quality all the way up and resolution to 640x480 or 800x600. This game really runs good on Riva 128 too.

If performance is low, try disabling Mipmaps in Nv3tweak.

OpenGL or

Direct 3D

Install Direct X6.

Use Direct 3D mode.

Tweak your computer out like hell!

Disable any extra features in the game you need to in order to increase framerates.

(direct draw)

This game tweaks the same as Subspace.

Install the 2.77 drivers and the latest version of Direct X. Using DirectControl right click the icon it creates in your system tray. Now, go up to Direct Draw. Choose DISABLE. Start the game and it should be run normal.
