Horrible frames. Getting frustrated.

I'm just taking the devs word for it. Maybe all the resources needed for the simulation is at hand all the time, even when paused. Just guessing...

CM does simulate some things to a deeper level than many big popular games. It's mostly about the spotting, and that's a key part of what makes the game interesting. But that's done in cycles, not continually.

And I think most of the work is done when you press "end turn" anyway. That little bar that fills up before you see the replay of the turn.

That there is pretty much the wet dream of this entire community. Who knows, maybe they are secretly working on an entirely new engine all along and one day we will be pleasantly surprised.

To be honest I hope they don't work on a new engine. Unless their simulation code is somewhat tightly coupled with rendering engine at low level, it would be a waste of time. Licensing Unity/Unreal would cost less. There are available technologies like Speedtree which make things much easier/faster. What is probably an obstacle is that code base is quite old and only a few people know it well enough to port it to modern tech.

Btw the game uses about 15% of my CPU on average and about 20% of GPU. Anecdotal data, if I have time I'll do proper analysis for fun.

The plus is it should run on virtually anything.

In July 2018 Steve posted something about game engines which I'm paraphrasing below: 

Eventually we will have a new game engine.  Obviously it will be written with contemporary technology in mind and won't be OpenGL as we view it as a dead end.  It will also benefit from 20 years of experience with how best to simulate tactical warfare on a computer.  It's only a matter of when, not if.

I play the game with average 60 fps sometimes dropping to 35 fps. I also can use reshade crazy like hell without any losses of fps.

My settings are:

3D Model Quality: Balanced (thats important!)
3D Texture Quality: Best
Antialiasing and V-Sync on in the game settings

I found that the nvidia settings are critical too for a good performance. When I use my graphic card settings for Antialiasing or Supersampling etc, then I lose about 20 fps. All my games have these settings (others not mentioned are default):

Anisotropic Filtering: 16x
OPGL Rendering: My graphic card
Power Management Mode: Maximum
Texture Filtering: High Quality
Lod Bias: Clamp
Trilinear Optimization: On
Vertical Synchronization: fast

My System: i7-8700k, 16GB RAM, GTX 1080 TI, SSD Drive, Windows 10 Pro 64 Bit

You have a CPU with 6 cores by any chance?

Some neglect to consider that a single core is only ever used... I've found little reason to swap my older CPU because of this.

I now have a dedicated 5+ years old PC running all my CM toys. The re's only so much a GPU will do for you and any card available 3-4 years does the job. The biggest consideration when it comes to GPU is whether to go Nvidia or AMD. While, I'm an AMD owner, I'd recommend Nvidia to avoid basic known issues concerning the in-game Shaders.

I'm using Nvidia and seeing shadows flicker on and off depending on camera angle (which also changes the lighting of the scene), and even shadows going in the direction of the sun instead of away from it. I wonder how the shaders would behave if I had an AMD based machine? :)

Yeah. 15% CPU is approx one core, you know what I am about here :)

And since CM is only using one core* that's nearly maxed out.

* There are a few places where multiple cores are used but that is during loading and initializing not during play - from what we have been told.

The flickering/lighting is to be expected to some extent given the free moving camera we enjoy. The only time it's really an issue for me is when I'm trying to pose a screenshot. Otherwise, I simply shift the camera position over a little.

My two pet AMD peeves are: 1) hit decals only show with shaders ON (white dots/holes when OFF) and; 2) depth buffer access is broken which precludes the use of certain interesting shaders under ReShade. I suspect, given the resources available, the effort is concentrated in at least ensuring in-game shaders render properly with Nvidia rather than AMD when both/all isn't possible. Which, I find to be perfectly understandable given the relative market shares.

I also keep the 3D Model setting by default on "balanced" or "improved". On a powerful computer and forest heavy maps it perhaps makes sense to go for one step further with "better" if one want to trade fps for distant tree draw distance.

However I never use the highest 3D Model settings in any Combat Mission title as it will severely disrupt FPS even on the most powerful machines without providing much if any visual improvement - at least for my eyes.

I don't see why those two things should be connected?

They are in the sense that it is simpler to efficiently produce a shader for a fixed camera position. The costs are in-game FPS and programing effort.  Personally, I'd prefer that they make it perfect for CM3 rather than spend scarce resources in an area so well supplemented by an open sourced post-processor such as ReShade.

I dunno. I only play a graphics expert on TV...

Have you tried ReShade to address your issue? It's a windows only solution but it goes a long way towards modernizing the look. It's most effective when used on older titles such as the CM2 family of products which can benefit (quite easily!) from the 'free' man-hours of effects contributors.

DeutschRitter's advice is excellent.

One other tip that I've very recently discovered is to use an older version of "Razer Cortex" to "boost" & optimize your system whilst playing Combat Mission.

https://game-booster.soft32.com/old-version/

Newer versions of Razer will also "boost" CM... but they unfortunately also disable Reshade. The older versions allow both to run.

Since adopting this technique I'm running about as fast as DeutschRitter... however I have a far inferior machine, an old i5, a 1050 Ti & 8GB of RAM.

I have, though not the old version but the new. I can't say conclsively that it helps or how much as I haven't done dedicated tests. But my impression is that it helps, especially in larger unit dense scenarios with weather effects added. It is quite easy to use. The only drawback is that some programs that you run might get reset to their starting point, like Acrobat Reader and iTunes.
