All games use mailbox/triple buffering. Except when you enable sync to
host refresh, in which case FIFO/double buffering is used.
This means vsync enabled will ever tear, but at the same time, never
drop to 30fps on a missed frame due to frame rate differences.
To have the "best of both worlds", you should enable vsync and sync to
host refresh. Previously, this resulted in additional input lag, since
the host vsync would drive the EE frame timing. Now, this behaviour is
disabled by default, unless you enable "Use Host VSync Timing".
[SAVEVERSION+] VM struct changes.
- Serial/title is now linked to disc, instead of running ELF.
- Save states can be created during BIOS boot.
- Patches now apply based on the executing CRC, and only after the
entry point starts executing (fixes multi-game discs).
- Add "Fast Forward Boot" option.
- Split achievements download and activation, downloads occur on
initialization, but are not activated until after the ELF loads.
- Prevent HostFS access while in PS1 mode.
- Remove multiple sources of truth for ELF/CRC/etc.
- Move ELF state from global scope to VMManager.
- Prevent game fixes and hw fixes being active while booting game.
- Simplify game update.
- Flush recompilers after ELF loads. No point keeping boot code around
which gets overwritten.
Move files from Frontend directory to pcsx2 and/or subdirectories.
Get rid of double GS init.
Combine HostSettings and Host.
Combine Frontend/Achievements.h and Achievements.h.
GS/DX11: Don't throw bad_alloc on surface creation fail

Fixes rendering at thousands of FPS when pausing if FSUI is active.
Avoids flickering when recreating swap chain in vulkan on menu open,
because we're no longer doing it.
Fixes bug where after changing settings in the big picture UI, if you
didn't have a game running, it would turn off vsync, making GPU go brr.
Also cleans up HostDisplay a bit, removing redundant parameters.
