All was working well w\ both Dx9 and Dx11 versions on my box yesterday then all of a sudden the Dx9 version will still run OK but at the opening screen the ingame mouse pointer won't scroll down to the selections now. It stops just above the menus then the mouse pointer will show up in the task bar. When I move the pointer to the right side the ingame pointer also stops approx. 2\3 of the way to the right then the pointer will show up at the far right edge. The only way I can access the menus is to move the clipboard as far to the top of the screen as I can so that the ingame mouse pointer can assess the menus. So far I haven't found the cause of this.
Now after doing this I then tried to run the Dx11 version. The opening screen opens just fine w\ no issues w\ the mouse pointer as I described for the Dx9 version, goes to the online selection screen, select Greebo's MA map then the game crashes. Tried over & over to find out what the issue is as all was working just fine before w\ no success.
Then I read your post, went & changed the texture size in Video Settings from 4096 to 512, saved then went online and all went thru OK. Exited the game OK then restarted Dx11, went in Video Settings, changed the texture size back to 4096 then went online and all went thru OK as well. Exited the game OK then restarted the Dx9 version but got the same weird mouse issue as described above but when I shut it down and restarted the Dx11 version all goes thru just fine now...........
Haven't figured this out yet but am working on this.
I have ran a full scan on my box, including a rootkit scan & nothing was found to date.
No other app\game I have is affected w\ the mouse issue except AH Beta 21 Dx9 version.
Working the issue...............
Update:
After working this issue some more I have found that the AH Beta 21 Dx11 version is auto setting itself in shortcut's Properties, Compatibility tab on my box to disable display scaling in game if it sees high DPI settings (this causes the opening screen to not scale to full screen and this was carrying over to the Dx9 version on initial opening which was causing the mouse issues...even though this is not checked in AH Beta 21 Dx9 version's shortcut Properties, Compatibility tab).
Now in Windows I do have my display scaling setting set for 150% scaling to make the texts and icons easier for me to see on the desktop @ 2560 x 1440 res and I have never noticed this to occur in AH in times past until now.
Now I also do note a dialog box opening on 2 occasions after I had reinstalled Dx11 and fixed the "3D3COMPILER_43.dll is missing" issue and had ran the Dx11 Beta that suggested that I might reset my Windows theme to Windows Basic (to disable Windows Aero...assuming due to either a conflict or due to 3D resources) but I did not do this. When I run the Dx9 version I have never noticed this dialog box to pop up in times past or even now. After the 2nd occasion I haven't seen it show up again.
Once I clicked on upper right box to maximize the screen this rescaled the window which fixed the mouse issue, even if I click the same box to rescale the window back to normal size and all stays fixed until I reboot my box which then the issue starts all over again.
Now that I know what's going on I can work w\ this but it seems that the Dx11 Beta version has an issue w\ desktop display scaling set above the default of 100%. I have unchecked this box, clicked Apply and run the game and upon closing the game then checked this in shortcut's Properties, Compatibility tab and found this setting rechecked so this is being done by the Beta 21 Dx11 version game reading the display settings.
FYI..........................
........
PS--I also remembered that since AMD's Crimson 16 series drivers there is a setting to set a game's display scaling setting in the game profile and I had this set to Full Panel (this profile works w\ both DX9 and Dx11 versions of AH Beta) so I also set this setting to Off so the Crimson driver won't attempt to set the display scaling as well since the game is auto setting itself by reading the desktop display settings itself.
So far, so good.
