I would have to concur - your free memory goes down to ~200MB, but you still have over a GB on the standby list that is basically free, because those pages have been marked to be paged out if your system needs that memory. Given you have ~200MB actually on the free list, they probably aren't needed when UT2K4 is running, although the dolphin Wii emulator is a memory hog (for legit reasons), so memory would help in that scenario. I would have to say that overall, though, memory is not really a problem here. In most gaming scenarios, it's going to be a CPU or video card bottleneck, and given we're talking about gaming, the latter is even more likely. However, the ATI Radeon 3200 in your system would indicate you're on a laptop, so unless it's a gaming laptop or an upgradeable one (not just RAM) you might not have many options at all to make the system play games better.
