Look, the fact of the matter is, with the frame limiter on, alot of the jerkyness from GTA/GTA:VC goes. Dispute it as much as you want, but ive seen plenty of people complain about poor performance, and it is then fixed when i tell them to switch on the frame limiter. THIS IS A FACT.
Im not the one needing to see an optician, as long as the frame rate is above 25fps, then it is smooth. Full Stop. THIS IS ALSO A FACT.
I find it funny that you say "people like me" and that you and BFG10K are always having to explain things to "people like me", fyi, in alot of threads that both BFG10K & me are involved in, i cannot recall us at anytime disagreeing. You seem to have it in your head that you know everything and that you are always right. No one knows everything.
You provide some valid comments about TVs, and you obviously know alot about them, i do not, and so i cant only go on what ive learned from various sources, however, when it comes to computer games and their engines, as well as the inner workings of a graphics rendering engine, i could probably baffle you with what i know, as you could baffle me with what you know about TVs. GTA was designed to run at 30fps. Just play GTA2 on a modern day PC with the frame limiter off, you could run accross the city in less than a minute, but with the frame limiter on, it plays at a normal speed. GTA3/VC are not as bad as this, but when the frame rate drops from the lofty hights of 80+ fps, to say 30-40fps, then the game will seem jumpy/jerky.
Its been said on the official VC forums that when the Frame Limter is off, then it can cause problems with the streaming, and that the streaming has been optimised for 30fps. When i switch off the frame limiter, and an speeding down a road at top speed in a PJC-600, then i can clearly see that the game has trouble texturing the building/roads at a pace that keeps up with me. With Frame Limiter on, the game has no such trouble. So streaming works best with frame limiter on.
People have got to get it into their heads that 30fps does not mean jerky, unplayable gameplay and/or better gfx quality. Look at DX2, Warren Spector himself has said that he is aiming for 30fps with DX2.
