Why does it run so much better on 1360x768?

Hey guys!

I've had the M11X R2 for a week now, and was running games at 1366x786. I thought that was the resolution to go. Then as I was playing Far Cry 2 and tried 1360x786, and then I was able to run it on high/very high with 30fps. With 1366x786 I would get 15-20 fps here. Then I tried about 5 other games: Was able to play bulletstorm with all on high, before I had to put all on low. Man I was happy when I found out about that resolution change. Just wondering why this is the case?

I love my M11x even more now. I bet every other M11X owner knew about this, I am still learning hehe.

 

I have seen this effect too and I really don't know the answer accept the fact that its 6 pixels less...I'd like to know more to the answer if there is more as well

 

It could be because it's 1360 and 768 are cleanly divisible by 16 (or was it 8), but no proof and no idea.

I tested this in Dirt 2 and I got the exact same amount of fps in the game

 

Its area, so 6 X 768 = 4608 less pixels. still there shouldnt be a noticable different between the two.

 

Bulletstorm with 1366x786 on the left and 1360x786 on the right. All settings are high. Can anyone with bulletstorm also try compare this?

 

wow didnt realise it has that much effect :O
any1 have any idea why this difference is so big?

 

though lowering the res to 720p should do better than 1360x768.

 

Maybe with 1366 you were just above a bottleneck point or something. That's really the only thing I could think of that would show such a ridiculous difference.

What was bottlenecking? Well I haven't a clue. Your pagefile, perhaps, maybe it was just at the point where Windows decided to dump a few things to your HDD, and fetching those back cost you those frames. Again, purely guesswork.

 

zero diff in DoWII and metro2033 after testing. Must be something peculiar with bulletstorm.

 

After restarting the machine I no longer see any difference in Far Cry 2, only see difference in Bulletstorm. Maybe it's only like a handfull of games that benefit from 1360x786 or something.

 

I'm guessing here, as I haven't looked into it, but it could be the best alignment to a 16:9 screen.

WXGA (1280×768) Wide eXtended Graphics Array

1280×720 Monitors, older LCD TVs 16:9
1280×768 Monitors 15:9 (5:3)
1280×800 Monitors 16:10 (8:5)
1360×768 LCD TVs 16:9 (approx.)
1366×768 LCD and PDP TVs and monitors 16:9 (approx.)

[extract from WiKi]
1280×720 provides perfectly square pixels at an aspect ratio of 16:9, while the additional pixels in 1280×768 and 1280×800 must be ignored to give the 16:9 ratio without vertical stretching of the image. 1360×768 and 1366×768 come very close to 16:9, displaying exactly square pixels if 1360×765 pixels of the display are used.

Some HD and Full-HD TVs have over-scan which need to be turned off to give a good PC -> HDTV match.

 

I believe this to be the case as well... and like some of the posters indicated, it may depend somewhat on optimizations within the game engine through to the graphics rendering.

 

Interesting. I can't completely test it, but this small fix seemed to make the keyboard respond faster in IE9 when I have both FFXI and IE9 open. It used to take several additional seconds to respond to a forum like this one.

 

Is there any reason why alienware went with the 1366 by 768 res instead of the usual 1360 by 768?

 

1366x768 is the usual...

 

what i meant was that all games come with resolution option of 1360 by 768 pre-loaded, not 1366 by 768. ofc the m11x pre-loadeds the option of 1366 by 768 cause of the screen size.
idk if that makes sense at all...

 

Never heard about this before? Games pre-load resolutions?

 

i use 1280×720 since it's a small screen anyway, wont notice much change unless i plug it on external. Plus it gives a huge boost in performance and i can turn on higher quality.
