|IssueName=Out of VRAM crashes

|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.

# PCSX2 versions released later than May 7th, 2016 should have much smaller VRAM spikes.

# Make sure Large Framebuffer is disabled.

# 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. Note in 1.7.0 dev builds Sparse Texture may be broken and cause problems.
