Fixes #17014 Even if our depth-testing-equal heuristic believes that the game needs lower depth resolution. This removes some depth-fighting artifacts (that are present on the real PSP, but nice to avoid) in Outrun, Split/Second and Cars: Race-o-Rama - essentially reverting these to the behavior we had before the heuristic. (The heuristic is good though - it means less compat.ini hacks going in the other direction). In the case of Outrun, this relies on two passes that pass exactly the same vertex coordinates twice resulting in the exact same final geometry. This is actually guaranteed by the spec if the vertex math is exactly the same and "invariant" is set on the position output, though I guess you never know.. Haven't seen any issues at least. Also sneak in disabling some validation messages from using extra Vulkan validation layers other than the default.

// Compatibility flags are controlled by assets/compat.ini.

// Alternatively, if PSP/SYSTEM/compat.ini exists, it is merged on top, to enable editing
|

// This file is not meant to be user-editable, although is kept as a separate ini

|
//
|
|
// The uses cases are strict:
|
|
// * Enable fixes for things we can't reasonably emulate without completely ruining
|
|
// performance for other games, such as the screen copies in Dangan Ronpa
|
|
// * Disabling accuracy features like 16-bit depth rounding, when we can't seem to
|
|
// implement them at all in a 100% compatible way
|
|
// * Emergency game-specific compatibility fixes before releases, such as the GTA
|
|
// music problem where every attempted fix has reduced compatibility with other games
|
|
// * Enable "unsafe" performance optimizations that some games can tolerate and
|
|
// others cannot. We do not currently have any of those.
|
|
//
|
|
// This functionality should NOT be used for any of the following:
|
|
// * Cheats
|
|
// * Fun hacks, like enlarged heads or whatever
|
|
// * Fixing general compatibility issues. First try to find a general solution. Try hard.
|
|
//
|
|
// We already have the Action Replay-based cheat system for such use cases.

// TODO: Turn into bitfield for smaller mem footprint. Though I think it still fits in a cacheline...
