So how CPU-limited ARE modern games using a G80?

[Jawed]

Admittedly my 22" CRT goes to 2048x1536, which does provide a degree of anti-aliasing!

Some laptop LCDs reputedly have quite high dpi, around 150 I think. So, if they just grew in each direction...

Nice, wonder how many pixels your crt can actually resolve?

Not very.


According to Anandtech Valve multi-threading article

http://www.anandtech.com/tradeshows/showdoc.aspx?i=2868&p=5

We've already seen quite a few games that are almost entirely GPU bound, so some might argue that the GPU needs to get faster before we even worry about the CPU.

People just throw around both terms according to their agenda, and they're both meaningless.

Looking at the G80 reviews though, most games appear to show good scaling even at the lower resolutions. In abscence of overclocking results a good way to guesstimate is if the FPS fall at each resolution step. AKA if there is a significant FPS drop from 12X10 to 16X12, then clearly 16X12 isn't CPU limited. Also if there is a big difference between the top cards and the ones below, it's not likely very CPU limited. Both cases apply to G80 in most games according to reviews.

Some of the resolutions used by people are getting ridiculous I think.

I mean 2560x makes sense if that is the native res of your screen, but screens don't need resolutions higher than that unless they are significantly bigger imo. And modern games certainly don't have the detail necessary for such high resolutions to make much of a difference, I think.

rendering to a higher resolution is great + downsizing it to the monitorsize is great its called supersampling ( a higher quality than most AA methods drivers use when u enable say 4xAA which only really helps on the polygon edges SS helps everything )
eg render it a 3200x2400 sized window + downsample to 1600x1200 with a fragment shader (if u wish more control)
3200x2400 -> 1600x1200
6400x4800 -> 1600x1200
16xAA anyone!! (i believe max texture size on the g80 is 8192x8192, though u could tile if u exceed that res)

The only time I have been able to get my CPU to be the reason I was getting poor FPS was when I installed 100+ mods into Oblivion. I had a fair share of mods that ran global scripts for graphics related information and they were just eating my CPU for breakfast. I have a 3.4GHZ Hyperthreading P4(I forget the stupid Intel number) and an x1900GT (the first released not the second). The easiest way to tell if your CPU is limiting your performance is to change the graphics settings. If you see barely any FPS hit when putting on the lowest graphics settings to the highest, it is a rather good indicator you are CPU limited.

I've wondered about that since I got my laptop with a 17" 19x12 screen. If that's possible on a high-end $2000 laptop why are bigger standalone LCD monitors with lower dpi's at the same resolution still costing $700-1000 ?
