This one lets you set resolution to whatever your video card will pump out. I dont remember whether it does all 4 views at once or only active, but it wont change settings

It saves to clipboard so you can paste it where ever to create any image type

There is also a “screen grab” type one that will just save a file for you. On petr’s MoI page. I’ll get a link then edit that in here in a second.
