      Special Upgrade 4 Tech Tips   12/27/2016

      Hi all! Now that Upgrade 4 is out and about in large quantities we have now discovered a few SNAFUs that happen out in the scary, real world that is home computing.  Fortunately the rate of problems is extremely small and so far most are easily worked around.  We've identified a few issues that have similar causes which we have clear instructions for work arounds here they are: 1.  CMRT Windows customers need to re-license their original key.  This is a result of improvements to the licensing system which CMBN, CMBS, and CMFB are already using.  To do this launch CMRT with the Upgrade and the first time enter your Engine 4 key.  Exit and then use the "Activate New Products" shortcut in your CMRT folder, then enter your Engine 3 license key.  That should do the trick. 2.  CMRT and CMBN MacOS customers have a similar situation as #2, however the "Activate New Products" is inside the Documents folder in their respective CM folders.  For CMBN you have to go through the process described above for each of your license keys.  There is no special order to follow. 3.  For CMBS and CMFB customers, you need to use the Activate New Products shortcut and enter your Upgrade 4 key.  If you launch the game and see a screen that says "LICENSE FAILURE: Base Game 4.0 is required." that is an indication you haven't yet gone through that procedure.  Provided you had a properly functioning copy before installing the Upgrade, that should be all you need to do.  If in the future you have to install from scratch on a new system you'll need to do the same procedure for both your original license key and your Upgrade 4.0 key. 4.  There's always a weird one and here it is.  A few Windows users are not getting "Activate New Products" shortcuts created during installation.  Apparently anti-virus software is preventing the installer from doing its job.  This might not be a problem right now, but it will prove to be an issue at some point in the future.  The solution is to create your own shortcut using the following steps: Disable your anti-virus software before you do anything. Go to your Desktop, right click on the Desktop itself, select NEW->SHORTCUT, use BROWSE to locate the CM EXE that you are trying to fix. The location is then written out. After it type in a single space and then paste this:

      -showui

      Click NEXT and give your new Shortcut a name (doesn't matter what). Confirm that and you're done. Double click on the new Shortcut and you should be prompted to license whatever it is you need to license. At this time we have not identified any issues that have not been worked around.  Let's hope it stays that way Steve

      Forum Reorganization   10/12/2017

      We've reorganized our Combat Mission Forums to reflect the fact that most of you are now running Engine 4 and that means you're all using the same basic code.  Because of that, there's no good reason to have the discussion about Combat Mission spread out over 5 separate sets of Forums.  There is now one General Discussion area with Tech Support and Scenario/Mod Tips sub forums.  The Family specific Tech Support Forums have been moved to a new CM2 Archives area and frozen in place. You might also notice we dropped the "x" from distinguishing between the first generation of CM games and the second.  The "x" was reluctantly adopted back in 2005 or so because at the time we had the original three CM games on European store shelves entitled CM1, CM2, and CM3 (CMBO, CMBB, and CMAK).  We didn't want to cause confusion so we added the "x".  Time has moved on and we have to, so the "x" is now gone from our public vocabulary as it has been from our private vocabulary for quite a while already.  Side note, Charles *NEVER* used the "x" so now we're all speaking the same language as him.  Which is important since he is the one programming them

Some problems with old gen CM on Win7 64-bit

Recommended Posts

Hello everyone, first of all I'm going to describe my gaming platforms, as a basis for the rest of the stuff. 1/ Notebook: Win7 64, Intel i3-2310M 2,1GHz; GeForce GT 520M; 4GB DDR3; 2/ PC: dual boot of XP SP3 32 and Win7 64, Intel Dual Core E6500 2,93GHz, GeForce GTS 250, 4 GB DDR2.

Ok, I've got no problems with running the games on my notebook or my XP-booted PC, while on Win7 on my PC CM:BB and CM:AK are stuttering and very buggy in display terms. For more info about the problem - few other games that work on my notebook or XP (like Silent Storm) also refuse to work (either graphical bugs or info about "GPU not found/compatible".

What can be causing it? My bet is that my PC GPU is unable to work properly with 64x drivers.

Try Alt-Tab'ing/minimizing CM (CMBB, CMAK) and then re-maximizing it. I'm not sure if this needs to be done once you've reached the 3D battlefield or if you can do it beforehand. This should hopefully get the games to run smoothly instead of the 'stuttering' that you're seeing. 

I'm also not sure why your notebook is not experiencing the same problem (since they both have GeForce video cards/chips). There is the possibility that the notebook is using the Intel integrated video rather than the GeForce 520M (which should be marginally faster). If you would like to ensure that the game is running on the Geforce, then you can create a profile for the CM games within the Nvidia Control Panel (Nvidia Control Panel > 3D Settings (left-hand menu) > Manage 3D settings > Program settings tab > click 'Add' and browse for the main game executables to create profiles for them (which typically has them launch on the GeForce GPU).

As you might already be aware, fog graphics will not work in Windows 7. The effects of fog will be in place for LOS, you simply will not see the fog in the 3D battlefield. Windows Vista and newer versions of Windows officially dropped support for fog-table effects in DirectX.

I've tried this on my notebook and nothing happens, BB and AK are working like they have always been.

But fiddling with it on my Win7 PC can help, I presume.

So the notebook, while running Windows 7 64-bit does NOT experience any problems, correct (the playback and scrolling around the map moves fine without stuttering) ? It is only the desktop computer running Windows 7 64-bit that has the stuttering, correct ? 

I can't remember if this problem became more prominent with Windows 8 or not. At first I thought that multi-core CPUs were causing the problem by possibly trying to spread the task among the CPU cores. Setting the 'affinity' within the Task Manager would potentially address such an issue (forcing the game to run on a particular core). However it turned out that simply minimizing the game in some manner (Alt-Tab, Esc, Windows Menu key, etc.) and then re-maximizing it would get the game to stop stuttering. It appears to be some sort of issue with the DirectX commands for drawing the 3D and/or 2D screens may be causing the stuttering.

Sorry for the late answer

 

I tried to mingle with CM on my PC Win7 and nothing changes, games still stutter. The problem is lesser if I change the resolution in the start-up setting, but still nothing changes.
