Not understanding Window Layout and Screen Resolutions
The issue: I simply do not understand how exactly Screen Resolution + Window Layout + Instant Switching works.
What I am trying to accomplish: A 720p (or other matching ratio to 1080p) resolution on 1080p native monitors - stretched to fit.
What happens based on my Window Layout: Game is locked at one resolution (cannot be changed in game) and is forced to 1080p because I have the main window setup as such (stretches to full the entire monitor). I cannot find a setting in ISBoxer nor WoW to override this, but it may not be possible given what I have set up.
What I do know:
1. A single WoW client can be run in a low resolution and simply stretched to fit the entire screen. If the aspect ratio matches you end up with a lower resolution just scaled up. Less CPU/GPU power and better FPS.
2. In ISBoxer DX9 config, you retain the list of resolutions in game (and can change them) and I think it stretches them out to 1080 based on my window layout yet I'm unsure if it took the lower resolution as my UI stayed in scale (or was my UI scale adjusted accordingly?)
3. Again in ISBoxer DX9 config or some other config possibly, when exporting you Can have the game in a different resolution in its own config, and ISBoxer warns you, and you can ignore that.
What I am not sure about (but can swear was the case):
1. I could swear there was a time, maybe back when I had less computing power, or wanted better performance, I had such a configuration whereby the game took up the entire 1080p screen yet was on a lower resolution (it was simply stretched) and instant switching worked.
2. The game profiles can be edited in InnerSpace and I have three: DX9, DX11, and WoW Default. One of which I may have edited at some point, but can't find much inside InnerSpace that shows me what I may have changed.
3. Again I could swear at one point my resolution was not locked by ISBoxer and could be changed in game, and then ignored the warnings when ISBoxer did an export.
I'm kind of at the limitations as far as what my machine can handle in large scale combat in these new zones with graphic effects everywhere and WoW's reliance on the CPU for graphical calculations (?!). I went away from the DX9 config a long time ago due to graphical weirdness and not-so-instant window swapping, and underutilization of my GPU. On the other hand if it's the only option now for lower resolution I'd like to maybe go back to it, since maybe a dozen or more graphical tweaks (CVars) were removed from WoW DX11 that allow you to turn off quite a bit of junk that does nothing for gameplay and IMO some of which don't make the game look any better but eat up CPU.
Hope that was all clear. What am I missing here? Thanks all.
