Great - at last my display problem for CMAK is solved. Thank you Schrullenhaft. I have bought a 4K monitor (res 3840x2160) and an ASUS GTX 970 graphics card so I wanted the best possible display. Easy - just delete the .pref file in the Game Folder in Programs(x86) and a restart will allow to set a higher res - maybe even 3840x2160. No way - shock, horror - there is no .pref file, and every time CMAK starts it throws up a very course and ugly image. But - Schrullenhaft has fingered the problem - after Vista, Windows writes the .pref file to a hidden folder. Perhaps I can find it !! not guaranteed. But, again - there is another way. Go back in time to before Vista, right click the CMAK shortcut on the desktop, click properties and open compatibility mode. Easy now - just select something before Vista (Win XP SP3, of course) and restart CMAK. Sure enough up comes the res selection boxes - first one offered is 2048x1536x60 - that's a 1.33 to 1 aspect ratio (native to CMAK) so I grab it. Display is great, panning a bit jerky but the control boxes are postage stamp size and too hard to read. So - delete .pref, restart CMAK (still in XP mode) and select 1920x1440. WOW - Is Good. Still one more thing - on NVIDIA Control Panel (right click the desktop) you get the choice of 'Aspect Ratio' or 'Full Screen' or 'No Scaling'. 'Aspect Ratio' gives you black side bars on the wide screen monitor - 'Full Screen' lets you use all the display but widens and flattens the Shermans (no bad thing) and makes the Tommies look even tougher. Forget 'No Scaling' - you just get a postage stamp (on the high res monitor) On the NVIDIA Control Panel you can also choose to let the GPU or the Display to do the scaling- I have chosen Display. And another last thing - the image which is displayed at any resolution is the same size and is the same portion of the map - just far superior quality at higher resolution. Up to a point which is determined by the game I suppose. Res is easy to set on CM -2 games using the display size.txt file in the game folder (not in Programs(x86) so it cant be snaffeled off sometime later LOL) I tried a few settings and settled for 2048x1536 (1.33 : 1 aspect ratio and 'Full Screen') The trees and water at Arnhem are beautiful and the cabbages in Ukraine are ready to eat. So, don't delay - go buy yourselves a Christmas present.
