It doesn't work. (For the software (i.e. non-Rendition) graphics engine, we have a copy of the screen in PCX format in main memory.) For the Rendition version, the only copy of the screen exists in the video card's memory. (Of course, we could copy it over, but that would a) take a while [you'd notice the momentary BLURP in framerate] and b) we didn't write the code for that.) So, instead, we just blurt out some random pieces of memory, which would be were the screen buffer was if you didn't have a Rendition card... I believe that this is NOT being addressed by the patch... ---Jim Sokoloff, Papyrus

It just didn't happen. (In fairness to the engineer(s) involved, the graphics engine is a complete re-write, which explains several of the *ahem* less desirable differences between ICR2 and N2 Rendition code, including this one...) --Jim, Papyrus

In N2 multiplayer mode with a rendition card, there are a couple of keys that you definately do not want to accidentally use in a chat message. Also, while racing, there are a couple of keys that you definately do not want to push, else your screen will freeze, the sound will continue, and you will most likely wreck. I suspected these had something to do with screen buffer copys? The momentary BLURP in framerate is there, it just does not work. Can the patch disable the key to prevent the accidental BLURP in framerate?
