Will 21:9 reduce my fps dramatically?

[BestBOTEU]

Hello, I was considering on purchasing the LG 25UM65-P (which is 2560x1080, but you probably know that already), and I wanted to know how much fps can such a resolution reduce as I currently use a 16:10 1920x1200 monitor. My rig runs BF4 on servers with 64 players, ultra, 2x msaa, motion blur off at 1920x1200 at a 45 fps avg

So my question is will the switch the 2560x1080 monitor greatly reduce my fps?

Thanks in advance!

What GPU do you have at the moment?

Not really, 2560x1080p is about 20-35% harder to run depending on the game over 1080p. With your res maybe 15-25% so it shouldn't tank your games but you will want to lower settings. And don't be a @Timopomer lol. It won't be that huge. I know because I have a  21:9 the monitor in question actually.

1920x1200 monitor has ~2.3M pixels, 2560x1080 monitor has ~2.7M pixels, that's increase of ~15%. I would expect drop in FPS around similar 15%. So if current FPS is 45, 15% less would be ~38FPS. Very rough calculations. Sorry, if incorrect.

You are starting to crawl onto 1440p resolution. I would highly reccomend getting a GPU update if you want 60FPS. A R9 290 or a GTX 970.

Sometimes that is fairly accurate but amount of pixels does not equate to gpu load. But then the negative effect of 21:9 is higher cpu load because you are adding much more objects (again depending on the game.) Sometimes it's no difference, other times it is.

Probablu, yes

This is super easy math.

1920x1200 = 2.30 MP
2560x1080 = 2.76 MP

 

Delta = 0.46 MP

 

0.46 MP / 2.30 MP = 20% additional pixels from what you are driving now, so you can expect to have FPS drop around 20%.

 

Alternate calc: 2.76 MP/2.3 MP = 1.20 => 20% higher pixels per image.

 

Drop MSAA or Textures and you can make that fps drop back easily.

alright thanks for the answers everyone
