I am just wondering, ive read a bunch of stuff saying that resolutions that are not exactly 16 or 16:10 might give some games a hard time performance wise ?
Any one knows anything about this ? |

I think it's simple math
1920/1080 = 1.77~
1600/900 = 1.77~
1600/1000 = 1.6
1366/768 = 1.778646~
etc |

| Shouldn't make a difference. |

Just a question though. Even though by your math the resolutions shouldn't make any difference, what happens when you factor in 720p and 1080p? Do these values change? Or could I just go buy a monitor with 1920x1080 resolution in 1080p and won't notice a significant difference in my gameplay in 1366x768.Last edit: 2012-05-29 02:48:48 |

The higher the resolution, the better the graphics.
But it's a two-edged sword. It also means more power required to run at that resolution.
You can play at a lower resolution if you have a higher resolution, but it doesn't work the other way around. Depending on what you expect, you might not be able to see a difference in 1366x768 and 1920x1080. Personally, I'd rather play with everything maxed on 1366x768 than on a lower setting at 1920x1080.
Basic 1080p monitors are so cheap these days that if you have to pick between it and any smaller resolution, you might as well get 1080p. If you're asking because you want to use an external monitor besides your laptop, I'd advise against it. Most laptop graphics cards can barely handle 1366x768. |

Okay, a monitor has a "resolution", usually indicated as [number]X[number], so 1920X1080, 1366X768, etc. This is the number of horizontal pixels versus the number of vertical ones. Of course, more pixels means you can have a bigger screen with nice quality, but at the cost of additional graphics processing, as your cards has to ""create"" (render) more pixels.
Aspect ratio, is the resolution in it's simplest ratios. So
1366X768 = 16 by 9. divide both by 85~
1600X900 = 16 by 9, divide both by 100
1920X1080= 16 b 9, dividing both by 120
It doesn't really mean anything, except that nowadays a common format is 1080p, and that means 1920X1080 pixels, so much HD content is natively (aka. meant for 16 : 9) which is why many consider a 16 : 9 screen advantageous. 720p, can also be easily converted to this.
For games, it's the total number of pixels that matters. Normally considered resolutions are 1366X768 (especially common for laptops), 1600X900, 1920X1080, and then the big 2560X1440. Not really sure what the OP's question is, perhaps this background will make it clearer to both of us? Notice, all of these are 16 by 9.
- No, there will be no significant performance degradation by any specific aspect ratio, not to my knowledge at least. The total number of pixels, as indicated by the resolution size, is what matters. What may make a difference, if you have a 1080p movie, which has the "native" (was recorded at and for) resolution 1920X1080 pixels, and you play it on your 1680X1050 or 1900X1200 screen, with aspect ratio 16:10, you may see black bars at the side, or the image may be slightly stretched. The quality degradation is likely to be very small though, I doubt you'd notice it, and you can always just play it safe and buy a "common" aspect ratio. It doesn't really matter anyway.
And to the poster above with 1600 divided by 900, and all that. I'm afraid that, at least to my knowledge, the horizontal number of pictures divided by the vertical number means absoulutely bugger all...Last edit: 2012-05-29 06:21:50 |

| He is talking about whether the distortion from the common ratios will cause more of a performance difference than what would normally be expected from changing resolutions |

What i mean the fact that the resolution is not 1360x765 (exact 16x9) has anything to do with quality. Also ive heard that the height should be divisible by both 16 and 9 for better performance, like 144 multiples, like in 1280x720 and 2560x1440. But actually dont know about that, i think i read something like that in the web. |

I don't know much about GPU rendering paths, but I don't see why it would make a difference, looking at the workload the GPU needs to handle to generate and display the image.
Looking at real-world benchmarks, there doesn't seem to be any penalty. 1366x768 results are just in line with what you would expect based on the number of pixels and the performance figures for other resolutions, which are exactly 16 : 9 or 16 : 10.
Also, 1366x768 is so common that it doesn't make sense for everybody to have adopted it if it led to issues. |
