|gameinfo          = With authentic cars, courses, and car physics, Gran Turismo 4 adds an even more realistic racing simulation to the series. The characteristics of each car take into account weight, speed, friction, and more to deliver realistic handling. Test-drive new vehicles in courses located in various sites, such as Nurburgring Nordschleife, New York City, the Grand Canyon, and Tsukuba Circuit. Along with Career mode, Gran Turismo 4 highlights the new GT Photo mode and GT Online mode, which lets players around the world compete over the Internet.<br />

* The MTVU hack may increase speed in quad core CPUs. This varies in dual-core CPUs as it may increase depending on the race but may cause slowdown in others.
* Other hacks can cause crashes or the game won't boot. This game requires a ton of personal tinkering to get it to run decent.This game also has very, VERY high system requirements (expect to use at least an i5 or an FX 6300 above). Don't expect a smooth or stable game. Slowdowns are heavy and very prevalent. It mostly depends on track, the lighting and the amount of cars on screen.
* EE Cyclerate can give speedup during the races, but may also cause slowdown to the track-selection screens where videos are shown at the background.
* The "Allow 8-bit textures" in GSdx may help with speed a bit more and maybe reduce the VRAM slowdowns.
* If you are using software mode and have 4 cores or more (this includes hyperthreaded cores, as PCSX2 takes advantage of this), set the "extra software threads" to the amount of total threads in your CPU minus one (4 cores, threads to "3", 8 cores, threads to "7", etc.). This can provide a noticeable speedup in any game running in software mode, but beware that only native resolution can be used.

# If you get lots of crashes during license tests use a lower internal resolution in GSdx.  
# To avoid crashes at the start of an event, temporarily switch to the Sofware Renderer by pressing F9.
# Multisample anti-aliasing(MSAA) can cause the game to crash a lot. Make sure the MSAA level is set to 0 in the GSdx Configure Hacks menu(only applies to Direct3D HW renderers).
# If you get lots of crashes during license tests go to Config > Video (GS) > Plugin Settings, and set Internal Resolution to (1x) Native, or set Renderer to any of the "(Software)" options.

# In Windows XP, even in native resolution, you may get instant crashes when starting races if you do not have enough VRAM. Using a custom resolution lower than 512x512 seems to help.

|Description='''(Hardware Render)''' Missing ground textures, textures in the distance flicker. This issue is present on the HW render because the game requires proper Hardware Mipmapping.
|Description=Missing ground textures and/or textures in the distance flicker.
|Workaround=There is no known workaround at the moment. Accuracy of hardware mipmapping needs to be improved in the code first.
|Workaround=Go to Config -> Video (GS) -> Plugin Settings, and set Renderer to any of the "(Software)" options. Then Make sure the Mipmapping option is checked at Software Mode Settings.
