Metal Gear Solid HD Collection [BLUS30847]

Here's an update using KD-11's vertex rewrite (found here: https://ci.appveyor.com/project/kd-11/rp.../artifacts)

MGS2 and 3 HD render, and are playable. There are graphical bugs which can be found in my screenshots (MGS3 screens to be added) but the games themselves are playable with variable framerate (20-60) on my system, an i5-4690k and GTX 970.

This reply will cover MGS2, and I'll make another one for MGS3

Significant bugs present are:
- Effects missing, such as rain and water underneath the tanker/around the plant. Other effects missing include the ZZZ on top of knocked out soldiers' heads and blood.
- Some particles such as bullets and vulkan's rubber pellets are missing, while others are present such as the M9 darts on hit soldiers.
- All lasers are missing, including weapon aiming lasers (for players and enemies) and C4 traps. The latter can't be seen even with Thermal Goggles (screenshot included).
- Other effects missing are the lice in the plant, rotors on helicopters and vent coverings/grates.

My settings are:
- PPU/SPU Recompiler
- SPU Threads: Auto
- No other SPU settings enabled (loop detection etc.)
- GPU: Vulkan
- Framelimit: Auto
- 1280x720 resolution

- I've tried the following, no noticeable effect unless mentioned:
- Write Color Buffers (MASSIVE slowdown, as much as 75%)
- Invalidate Cache Every Frame
- GPU Texture Scaling
- Strict Rendering mode
- VSync
- Stretch to Display Area
- Disable Vertex Cache

I was able to play through most of the Tanker chapter before loading up the Plant chapter. The game crashed around that time with the below, after more than an hour of continuous gameplay.

E {rsx::thread} RSX:
