|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 />

|Comments=Runs at full speed, both software and hardware mode. Note that GSDX hardware mode had a graphical bug where the wheel rims are being offset, resulting a shaky wheel when viewed under replay, software mode are unaffected. Meanwhile, software mode requires a strong CPU with at least 6 core and above to emulate properly, CPU usage on all cores are at about 50%-60%. License test bug happens on license iB-5 where you may require to disable automatic gamefixes first. Also, be warned that continuous loading savestate will causing the game unable to perform save, citing the game save is corrupt. You can only fix this issue by deleting GT4 game save from memcard browser and load the savestate and save the game, but you will lose all cars except the current one that you had drive.

|Comments=Completed a large chunk of the game. Good emulation these days, game ran mostly full speed at 6x native resolution with no speedhacks, but a handful of tracks needed the resolution to be reduced to 4x. Run the game in OpenGL mode for proper brightness. Ensure Blending Accuracy is set to at least Basic, and Conservative Buffer Allocation is checked. In Emulation Settings > GS Window, change Zoom to 100.20 to remove some garbage from the edges of the screen. Special Stage Route 5 and George V Paris are the most intensive tracks to run at full speed, and you'll get your lowest framerates here, so they're good benchmarks. A few minor visual bugs remain. "Get ready to drive" will be stuck on the screen even once you gain control of the car. This can be fixed by just pressing Select (to change view). The NTSC version of the game is preferable due to its 480p mode, and the game is hideously interlaced without 480p enabled. Final note: be very careful using savestates in this game, if you overuse them you can corrupt the memory card. Not just the GT4 save, but the entire memory card. To prevent this, ensure you never load a state from before the memory card was last saved to.

|Comments= Fully playable, no crashing in License Tests, minor FPS slowdowns (2-6fps) and minor graphical glitches related to light sources, such as flickering headlights, sun and lamps that can be seen through walls, and lens flare going full rainbow mode. Visuals can be enhanced further by activating 480p mode, using the secret menu to modify the FOV, FXAA (big fps slowdown on city courses) and external shader settings. If you need tutorials on these, search for Rowdy on YouTube. OpenGL and Direct3D look and perform identical for me; Vulkan fights its way through as well but it's a tad slower, still worth giving it a try. Game runs and looks as awesome as ever.

Some Licence Center tests (B-3 being the first) will crash if you don't set both Clamping Mode settings to "Normal". Unfortunately using "Normal" causes some graphical issues so you'll have to change the settings for your Driver's Licence tests and then swap back to "Full" and "Extra" for the rest of the game (see my settings). Same setup as the NTSC-U test. Didn't test the game that much, but I'm assuming there are no region specific issues.

|Comments=
Mostly stays at a steady 60 fps during the races. The odd drop will occur. George V Paris (which seems to be one of the hardest to emulate) race track works fine at full 60 fps; but there will be the odd drop again to about 50 or even 47 fps. Otherwise, pretty playable. Funny how this is a CPU intensive game. But apparently the lower EE Cycle rate, higher the EE Skipping rate and without MTVU enabled, the better the game performs (At least in my case). However, there will be screen shaking. To reduce that, go in the game options and under "Screen," change the screen to "HDTV 1080i." That should reduce the screen shaking during a race. But when going through some menus like selecting a race course, there will be screen shaking. Otherwise, the game works decently enough to play.
