Resolution performance?

New years resolution! Good one. Onto you post. The link is empty, so I'll go with the two games you listed. Yes, a high resolution means more work for the graphics card, and unless your cpu is capping your fps (possibile for MMO) or you're using a high gpu (you're not) you may see FPS drop or have to lower GPU intensive settings like AA. That said, I think you'll be ok, the resolution is still lower than "standard" these days.

keep in mind this without any mods or packs

Hi Dijas,
I loved my 1680x1050 monitor!
The 16:10 aspect ratio is just that little bit more 'Imax' than the typical 16:9...
16:9 is like looking through a mail slot, heheh.
But nobody sells 16:10 anymore - they are extinct.
Top-o-the-line dream monitors, for years, were 1920x1200 (16:10).
You try to find these now? You can't.
The whole world is looking through their 1920x1080 mail slot these days...
It is unfortunately the only game in town.
My beloved 1680x1050 monitor died about 6 months ago, and I picked up a new 27" LG for pretty good deal, $269 bucks. It is 1920x1080.
I didn't really notice a performance drop moving to the higher resolution.
But Tommy's testing shows a small but distinct drop in FPS - maybe 4 to 5 frames.
So yes, you will not get quite the performance you had with the previous lower-resolution monitor.
But close! And you're one of the lucky ones - 16:10 is fantastic (if you can find one).
Again; I want 1920x1200 but it's just impossible... >sniffle<
Ah well, life goes on...
Regards

Performance decreases roughly proportionally with the resolution increase, as a general rule.

So it's an OK expectation to expect a 10% performance decrease for a 10% resolution increase, for example.

Ok, a 5 fps drop is very reasonable. I'm not sure why the link isn't working, but these are the games I'm playing a lot right now:

Team fortress 2: (I get easily 180+ fps on this game so I'm not worried)
Planetside 2
Metro 2033
Left for Dead 2
Crysis 2
Counterstrike: Global offensive

You have to look, but 1920x1200 monitors can still be found. I got my Dell U2412M about six months ago, and I LOVE IT!
