Interesting - I had a nice high end 21" CRT at one point I got for free when some tech company went under and told the building maintenance to just trash all of the brand new equipment. Luckily my uncle was that maintenance guy and I got free pick of whatever parts I wanted before it went to the landfill.

I do remember being VERY good at the original counterstrike (pre v1.5) comparatively - I know CRT's have very low input lag - I wonder if I was playing at higher fps / hz and didnt even realize it!

From what I remember VGA could actually do some decent resolutions (SVGA and whatnot were more limited) and DVI was starting to rear its head around that time as well. I vaguely using a resolution like 1900 x 1200 which is about what a modern 1080P HD is doing (slightly higher in fact)

Now this is making me wonder how my plasma TV actually compares - from what I remember plasmas do not have a "hertz" so to say but also werent really coveted for gaming (although burn in may to be to blame for that). Input lag on it seems decent but I would guess might be its big limitation. Surprisingly it does do 10 bit video and while it wont accept an HDR signal I suspect the display itself is capable of showing more dynamic range than many of the cheaper "HDR" LCD's

I'm pretty sure I was playing Counter Strike at, as reported by the game, 99 fps on my Sony Trinitron back then (2000?). We'd use "low poly" mods (simplified 3D characater models) to speed everything up and reach these speeds.

There are still messages on message boards from this era where several people mention reaching that same 99 fps.

It was two decades ago but I'm pretty sure it was 1024x768 @ 99 fps (19" Sony Trinitron). I may be mistaken on the monitor though.
