|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). Other than that, I haven't found any issues.

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.

|Description=PCSX2 crashes during or at the start of a race, often with GSdx Out of memory warnings in the log.
|Description=When launching the first race of a play session, VRAM usage jumps significantly just before the race preview screen starts. After the first race, this problem does not happen again until the next time you boot the game. The game will also have occasional VRAM spikes as it continues to run. Either of these can potentially cause a crash if they cause your system to run out of VRAM.
|Workaround=<br>
|Workaround=<br>
# In recent PCSX2 GIT revisions as of May 7th, 2016, VRAM spikes have been greatly reduced.
# PCSX2 versions released later than May 7th, 2016 should have much smaller VRAM spikes.
# Make sure you have "Large Framebuffer" disabled on the recent GIT revisions as it can amplify the VRAM spikes when enabled.
# Make sure Large Framebuffer is disabled.
# To avoid crashes at the start of an event, temporarily switch to the Sofware Renderer by pressing F9.
# To avoid crashes at the start of the first race of a play session, when on the loading screen with your car's name and tire types, wait for the loading circle to abruptly stop; this is a sign that you have run out of VRAM. Hit F9 to toggle between hardware and software rendering and wait a moment for it to respond. Once it changes renderers, wait for it go around a few more times, then hit F9 again to return to your desired renderer. This refreshes the emulation state of GSdx and clears the bad VRAM. If you notice that it never actually stalls out at all, you may still need to clear the VRAM and should hit F9 twice to do so before starting the race.
# To reduce VRAM spikes further, Nvidia users can Force Enable Sparse Texture in GSdx Advanced settings & hacks. OpenGL only.
# To reduce VRAM spikes further, Nvidia users can Force Enable Sparse Texture in GSdx Advanced settings & hacks. OpenGL only. Note in 1.7.0 dev builds Sparse Texture may be broken and cause problems.
