I know I don't have the best nor the newest computer in the world, but I can still play more complex (and heavier) games than this and still do it moderately soft and fluidly. But with Kingdom Rush (HD) seems like the ram goes crazy, reaching peaks of 1,5GB consumed ram over time, making long loading screens and a pain to have to wait or see the computer fighting against it.

Let me be honest: This is ridiculous.

While the flash versions are so lightweight, faster, simpler and resource-less... this big fat is eating my Ram like Pac-Man.

My question is: Why? WHY THAT HAPPENS?

Specs:
Windows XP SP3
AMD Athlon x2 3600+
2GB Ram
Nvidia GeForce 9500 GT 1GB

Any idea?

PPS: And yeah, XP blablabla. Got it already xD

Do you have an integrated graphics card in addition to your regular graphics card? If so you might need to manually set which card to use. For some reason Kingdom Rush likes to default to the integrated card - which slows things down a lot.

Yes, I have. Some another Nvidia 256MB integrated in the mother board, but it's disabled (?) by the bigger one so...
And I don't see what has to do the GPU with the computer RAM. ._. I've played some Unity based games. None of them were that resource eaters than this. And I thought Unity would be resourceless if well optimized. Yes, I'm starting to think devs doesn't know how to optimize. Because eating 30mb from a .swf at the most to pass and eat 1,5GB ram... that's a lot. ._.

Anymore ideas, guys?

In your Kindom Rush folder is a folder called "Kingdom Rush_Data". There is a file there called "output_log.txt". Open it up and look at your Renderer. If it is your integrated graphics then the game will eat up your RAM like candy. Don't know why it does that but it will.

Made a look on there and NOPE. It says is (I'm) using my main GPU. You given me great hopes and now I'm still at the same as the start of this thread xD

Thank you so much anyway.

Still looking for a solution. Help, please?

I've had basically the exact same problems, and I emailed the dev's tech support like two weeks ago, and still haven't gotten a response. I more than meet the system requirements, but the loading screens regularly take up to half an hour (!). My output log says the game is using the primary graphics card, but it has to be lying. I don't have a way to force the game to use a different graphics card, as far as I know- some Nvidia cards have an option to force a program to use a certain card, but only ones with "power-saving GPU technology", which I guess my card doesn't have.

There are a few posts about the problem on the Steam forums and [url=http://steamcommunity.com/app/246420/discussions/0/540738052809814466/]here. They haven't been of any help to me, but maybe there's something in there that could help you.

Oh god. I remember with Expeditions: Conquistador I could only play the game for certain periods of time because of it's outrageous RAM hogging. I guess free doesn't necessarily equate to good (engine wise).

So is that the reason why there are black boxes in my game sometimes?

Yeah, I'm noticing that Kingdom Rush is using about 1.5 GB and I'm running Windows 7 with plenty of RAM. This looks like it could be a possible memory leak in the game.

I just bought this game after playing lot's of the flash version.

After launching the game it crashed the game as I ran out of memory. It also corrupted the save game slot, and I had to manually delete the save files in order to play the game.

After that I lowered the resolution to somewhere around 1200. I also increased the animations in to full detail. For comparison the resolution on flash version is probably only something like 500.

The game is working now though it likes to use lots of memory. I think the engine is just bad. Ain't memory leak something that eats constantly more and more memory as you keep the program running? I have not noticed anything like that. Only that it likes to take a lot of mem immediately.

On web browsing I use Opera and I have to restart it after a couple of days. It seems to have some real leak and never frees the memory otherwise.

Just to add to the chorus.

I'm running XP, and it takes 5-10 minutes to load each level. Needless to say, there's really no point in trying when I can just go play a browser version.

I'd like to play this, if only to access the additional content, but it just isn't worth it.
