XCOM Aspect Ration and Gamma
« on: September 19, 2020, 05:25:34 pm »
Obviously XCOM renders image int 320x200, because DOS, but old CRTs still displayed 4:3. Old CRTs also had very different gamma curves from the today LCDs: on CRT picture looked much more brighter and contrast. Therefore the question: should one correct the gamma and the aspect ratio, while making mods and just playing the game?

Here I've scaled TFTD screenshot  to 640x480, which makes game look very different from what you will get with OXC or DOSBox. In fact, characters now have proper proportions.

OXC has a (hidden) option for 4:3 ratio (nonSquarePixelRatio: true).

Modders went the other way and decreased the brightness and contrast even more. Such a shame :(

nonSquarePixelRatio: true works only at 640x480 but it does not look good, pixels looking downwright ugly, bosbox has this much better implementet.

and with dosbox i get 4:3 in every res. Will this be addet in openxcom, too?


the whole thing (ui, graphics, etc.)  looks totally out of proportion without real 4:3.


please fix this with propper 4:3 like dosbox.

Sorry but you have no idea what you're talking about. Almost everything you said is false.

This is with dosbox 4:3 (4k too)


OpenXcom 4k Letterboxed (and nonSquarePixelRatio: true - but this is not working)


And lastly from a crt real 4:3 on real hardware with dos.

There one can see how streched everthing is, ui, graphics etc.

Besides that, the globe was never round in the original on classic monitors.
Like NashGold has written, too. "In fact, characters now have proper proportions."


OpenXcom is an asolutly beautiful Projekt, one of my all time fav games.
I hope 4:3 like in dosbox can be added in the future. (or an option that makes it scalable? So that the widescreen graphics are not stretched if one wants it.)

It seems to me that the reason as to why they appear different is due to the mission's light level. The one on dosbox seems to be running on a semi- night mission compared to the OXC screenshots

The last screenshot is the original tftd with dos. The streched barracuda with OXC is very visible for example.
