The company on the other hand has been very forthcoming about everything to date. There is no secret about the display. The way it works has been discussed ad nauseum. At 75 it uses the same lossless compression as the others. Due to a bottleneck to the chip that drives the displays, it can't process full 90fps at the typical 3:1 compression. So they added additional compression that fits into the data pipe showing at a lower resolution. The de-compression at the chip before driving the displays at full resolution has been over simplified as uprezzing, but since that is the number you see, people are running with that. So be it. The biggest issue is that this is confusing and the oversimplification is easiest description. If I understand it correctly, the utility that switches between 75 and 90fps enables additional compression before it gets to the native Steam VR which then displays the compressed data size which shows in resolution.
