| From what I can tell, AAA devs typically target compatibility

| equivalent to mid-range gaming rigs at best. Then they work
| on PC compatibility afterwards and poorly optimize
| performance of their assets against a common GPU
| compatibility layer that adjusts the features it enables (if
| they exist in this version of what's likely a shared
| underlying game engine) based on hardware compatibility.
|
| If we're very lucky, the game will get tested against a wide
| range of hardware. Sane defaults for GPU feature flags based
| on detection of hardware capability and the results of that
| testing will result in a default user experience that doesn't
| need manual adjustment. If we're lucky.
|
| So tl;dr, they're not targeting the top 1% of hardware.
| Typically they just screw things up and don't catch it. But
| higher end hardware will handle poor optimization better and
| provide a better experience. So it can feel like they're
| 'targeting' that hardware when really its a poorly optimized
| port.

| That wasn't the main point though. The point was that a few

| 70 series cards, for around 300 to 400 USD price point. Now
| with the 4000 series, the 60 and 70 series silicone have the
| specs of the older 50 and 60 silicon, at much higher price
| points.
|
| Nvidia is now selling us less silicone die for way more
| money, and their sales numbers reflect that.
