I haven't had a memory leak problem.

I think it's either straight-up memory leak, or a combination of memory leak and excessive caching of assets.

However, like Flagyl, I have significant system RAM, so I don't at all mind if the game wants to keep every last thing it's ever loaded in memory. Of course, I do have an issue if it's reloading the same thing multiple times and leaving it there (which is basically what a memory leak is).

*cough* You're using incorrect size annotation, and we're "noobs"? Nevermind the fact that "noob" is extremely derogatory and could, quite frankly, be taken as a personal attack, which is *probably* against this forum's rules.

There are several factors contributing to this game being slower than it should be. The typical "modern systems are faster, so we don't need to optimize code" motif another user mentioned in a different thread is probably the worst (far more damning than some memory leak, which, even if the game *can* only requisition up to 4GB of RAM, is still no problem for a good-or-better gaming rig). When I get large city combats and I can practically FEEL the game chugging through logic processes for each AI unit, you know something is seriously wrong with the code cleanliness.

I mean, I have 8 gigs of ram and it still gives me a problem. It isn't my computer. This is the only time i have ever gotten such a message from any game, and since its beta i assume a memory leak. It could be a data storage problem like another user mentioned (game holds on to everything it generates) but I think not. Easiest way to test it, and I will test it tomorrow, will be to just turn the game on, load a file and AFK for a few hours to see if I get the the memory issue. Ill post my results.

I would like to add that my Ram is filling itself up to 1.4GB for LH alone after just a few hours (normally 1-2,3).

When I play a modded HighRes Skyrim it doesn't eat that much of my RAM, so my guess is, that there is definately going something shady on, behind the curtains of the RAM.

I am eagerly awaiting the report of you two guys above me.

Well, since I shut off my internet connection when I am not using it (4G modem with usage cap),LH will be waiting for a while to upload it the cloud it can't see, then.  I don't remember enabling that option in Steam, however.  I will need to check into that.

Thanks for the info!

I've definitely noticed some nasty issues that appear to be a memory leak. After a few hours it leads to slowness / laggyness, followed by UI elements starting to disappear, followed by a crash. Playing on Win7x64 with 6 GB ram. Restarting the game once the warning signs appear fixes all the issues for a few hours.

Okay thanks I'll give that a try.

Frogboy suggested updating video drivers. But I for one always keep these up to date just because it is esssential to a good performance.

Also the game not closing itself is NOT the game loading saves into steam cloud. The steam synchronization happens AFTER the game is completly closed (either normally or by Task manager).

I can confirm I have a similar problem.

The more I play, the more memory the game allocates and the slower it runs. When I quit, close the program, and start it again, the interface is suddenly fast and responsive, but after some time, it starts to slowly gum up again.

Don't know if "memory leak" is really the term that is appropriate, but it does seem to allocate more and more resources. If it was justified, how comes the program is capable of running fast immediately after reloading? Maybe it keeps some AI related tables that are not stored in savegames, but in any case, it's suspicious. 

My drivers and DirectX are always up to date.
