AMD driver issues

[Margen67]

See:

• #1251
• #1774:

  [2:20 AM] TriΔng3l: That crash with ROV still happens, I'm going to make a workaround for a part of the cases soon though
  [2:21 AM] TriΔng3l: well, not really a workaround, just a slightly different approach of doing the same thing
  [2:29 AM] TriΔng3l: manual ddx/ddy of SV_Position.z instead of EvaluateAttributeAtSample, should be better for some other reasons (easier depth biasing, fixed-function viewport handling)

Xenia have regression in Gears 2, 3, judgement on Vega 64 GPU. Approximately starting from june 23 2020 main and on newer builds. I have TDR driver error.

On 20.2.2 and newer drivers, I had recurring crash in Gears 2 on beginning game on helicopter fly in cutscene. If i downgrade driver to 20.2.1 (february 2020) I can safely watch the helicopter scene. But I had a recurring crash in the belly of the worm. If i downgrade driver to 17.8.1 I can pass a moment in the belly of the worm. On any drivers, I also have crashes in random places that can be passed if you restart the game. On the very first driver for my video card, the error still appears constantly, but in a different place.

Xenia june 7 2020 maind build and the previous there are no TDR crashes on any version of the driver.

Same in gears 3.
