Add special game perf workaround for Starfield and other DGC junkies

From what I gather, FOSS developer for GPU drivers discovers Starfield code is of poor quality and highly inefficient. So this person writes and submits a “special game perf workaround” for their inefficient use of D3D APIs.

Honestly, this is out of my domain but I can safely say this is a problem for anybody that develops any library, api, or public service. This particular comment on the PR hits hard:

> It's sad that developers can't take their time to properly code their games due to their greed for money, and people like you, Kristian, have to fix their mistakes.
