I would be interested to see if there is any difference. I tried looking up different versions of PQ2. There are different version numbers on different disk releases. Not sure what version the GoG (or Steam) ones are supposed to be.
Well, I confirm that the GOG release is different! There is a speed difference on the intro screen. A quite pronounced difference when L1 cache is enabled. Less so when L1 cache is disabled. The non-GOG release plays at proper speed even running the game with L1 cache enabled.
Also there are differences in the resource files and EXEs. See photos below. In each photo I did DIR to first see what's in GOG release then DIR to see same list in this unknown release:
The attachment 20241031_071333.jpg is no longer available
The attachment 20241031_071239.jpg is no longer available
I note also that the GOG release seems to have copy protection in it. It asks me to enter the last name of someone from their photo. But in the GOG manual I can't see any names next to the photos. So I had to Google for mugshots with the names. Surely the GOG release must have the answer to the question somewhere in the documentation?
The unknown release I have seemingly has copy protection removed.

FWIW, I tried again slowing down my Pentium MMX 233. I set it to 120MHz (slowest the motherboard will allow), disabled L1/L2 cache, and used an ISA video card (Tseng ET4000AX chipset). Even with that, it wasn't slow enough for Police Quest 2. 3DBench reported 10.7 FPS. This is about 2.7x faster than my 12MHz 286, which gets 3.9 FPS on the same benchmark.
Note also that I am running this system with 72 pin EDO RAM. Considerably slower than the 168 Pin SIMMs (this motherboard supports both).
