When in the designer occasionally sound skips and sounds weird, my cursor drags, and thinks happen a second after clicking along with frame rate lag. I think its ram as it happens after 10-15 minutes in the designer mostly, although its happened on the galaxy map too regardless of map size or turn. Sorta makes me wonder as galciv3 uses about 4-4.5GB of RAM for me and I got 8GB (that I've optimized) so I have 4 left, so it has to be spiking.
So ya know.
