I will take a look the demos but when I went from a 60hz monitor to 144hz I personally did not notice any difference in game play with CS. Its only really noticeable in more modern games which require stupid GPUs to run on max settings. The only recoil issue I have atm is the M4 spray, tends to lag out visually but the bullets are still getting fired at the right rate (this is on DD2 with 25-50 ping). I have yet to find out why this is ://
And did you configure the launch option to put 100hz+~ (-freq 100)? Even tho you bought a monitor which says it's 144hz doesn't mean it's 144hz always with everything it's set at 60hz normal, + it's a LCD/LED monitor which has ms delays, while CRT has none.
Oh also he uses 640x480 resolution on a 19" CRT 100hz monitor, you won't notice a difference with high hz with really high resolution in cs 1.6
but you will notice how the aim is alot better on lower resolution with high hz.
Yeah exactly ^^ but I've been having problems with the -freq 100 command in launch options so I have to use Refreshlock to
lock it in 640*480 @100.8 hz 
Its constant 120hz and boost upto 144hz. So its still twice the refresh rate I previously had. Still no change. FYI my monitor is a Benq XL2420T, which is arguably the best gaming monitor of the last few years aside from maybe Eizo. The difference between 2ms and a CRT is not even visible to the human eye. We are going into this refresh rate and all pretty deeply, lets just leave the top players to sort out you unban request.
It aint constant 120hz, it's normal 60hz until you change it urself, and the 144hz thingy is mostly only for 3D, and if u didn't feel any change getting alot more hz ingame (be sure u actually got 100/120hz in cs 1.6) then u must be super bad, ask any real professional players if they want to play with 60hz instead of 100/120hz, they would say no because of how the game works with higher hertz, higher hertz = better recoil and smoothness. It's also alot better to play on lower resolution (640x480) with 100/120hz to get the lowest recoil you can.
And you say "lets just leave the top players to sort out you unban request." What do you mean by top players? If anything me and Kazi have played cs for 10~ years almost even tho we played at "pro" level few years ago we just play for fun now and we still have some of our skillz, but that is according to some of u folks = "hax".
