      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

CMFB: Heavy lag with falling snow

Recommended Posts

I just bought CMFB and noticed I get lag when it's snowing. The snow will fall smoothly for about 10 seconds, then the framerate drops a lot for 2 seconds and then back to smooth framerates. It's not just the snow effect that lags during that time, it's the whole game.

(also, when I move the camera, the snow effect will move with it, which looks a bit weird...)

Quick question, do you by any chance have a hybrid SSD/HD? In that case put the game on the SSD partition. I had a similar problem and it is related to sound. Try in game to turn sound off. If the problem disappears put it on the SSD partitiion.

Also have a look at the video card performance threads and try out the frame rate limiting settings - they help to smooth out frame rates.

Nope, I'm running the game off the C drive, it's a pure SSD, no hybrid.

Also it's nothing to do with sound.

I found out a further interesting thing:

I get the problem in the tiny "Die Patrouille", but not on the much larger "Breaking the line". Both maps have falling snow!

The only difference I can see is that the former has "heavy snow" and the latter "light snow". So it seems to be a problem with the heavy snow effect.

Jep, just tested it. I changed the snow in Die Patrouille from heavy to light. Fixed the problem.

So, it appears the heavy snow effect has optimisation issues.

Yep, „Die Patroullie“  (resp snow) is a real performance killer. On my old computer, with GeForce 570, unplayable. But a good excuse to buy the new machine.

There are two more scenarios with snow, which may slow down your PC, but not to the extend of “Die Patrouille”.

Every snowflake is uniquely instanced as they occur. CM starts with a microscopic airborne particle, and then simulates super-cooled water molecules accumulating around it. Obviously, the H2O molecule's propensity for a 6-sided structure is modeled. At the sub-atomic level. (Charles is using some string theory here, I believe. 11 dimensions and all that.)

Next, the flake grows. It's terminal velocity, interaction with other snowflakes (always giving each other safe space, naturally), updrafts, random motions, and various other aerodynamic effects are all modelled...in real time, as they fall. 

By the time you see the snowflake on your screen, a veritable epoch's worth of history has already been accumulated...for each one.

It's no wonder a setting of "heavy snow" can slow down those of you with lesser computers.

Or, it just needs better optimization. I prefer the previous hypothesis. ;)

I was wondering if anybody would make a joke like that :D

If you want to play it, just go into the editor and change the snow from heavy to light. It will change the visibility a bit of course, but I didn't notice any big diference when playing it through again. Snow lag was gone though.

No worries. Like I said: It was a good excuse to buy a new computer. 😎 And the new one copes very well with it.
