Legion Hardware performed some benchmarks to see how the retail, full edition of Gas Powered Games' Supreme Commander stacks up against today's computer hardware:

The graphics card is obviously another key component to improving performance, though unfortunately the latest and greatest solutions again do not guarantee stellar performance. Having said that, anything less than a Radeon X1950 Pro is going to make life difficult when playing on the larger maps with more than 2 players. In fact, using the low quality settings at 1280x1204 saw the X1950 Pro render just 24fps on average. The ultra powerful GeForce 8800 GTX was not a great deal better, producing an average frame rate of just 31fps. The maximum in-game quality settings saw the 8800 GTX fall to an average frame rate of just 22fps.

Based on the results we recorded it is clear the GeForce 8800 GTX is being limited by something else, most likely the processor. Looking at the high quality Intel Core 2 Duo E6700 results we see that anything faster than the Radeon X1950 Pro (7900 GTX, X1950XTX, 8800 GTS and 8800 GTX) benefits greatly from higher processor frequencies. The average frame rates continued to climb when using these four graphics cards, as the processor frequency was increased. The very same thing, possibly to a greater degree, was found when testing the AMD Athlon64 X2 processors.

Therefore, it is clear that this game is heavily reliant on raw processing power, probably more so than rendering power, though they are both very important. What I did notice; and for those wondering why we only tested with 2GB's of DDR2 memory and did not use 1GB and 4GB configurations, please let me explain. In the past we have tried to prove the worth of 2GB memory kits when compared to smaller 1GB kits. While we could physically tell the difference when playing games, the average frame rates never really seemed to change, at least not enough to justify the added cost. Unfortunately, when moving from 2GB's of memory to 4GB's with Windows Vista, the same problem presents itself.

Nevertheless, using Windows XP first I did test Supreme Commander with 1GB of memory which was just plain awful and then 2GB's which, was a vast improvement. However, after having measured the performance with 1GB and then 2GB's of memory, I noticed the frame rates hardly changed, with results increasing as little as 2 ~ 3fps. Therefore, I did not want to include more pages of graphs that show near no difference in performance and rather decided to discuss this issue. After testing these two memory configurations in Windows XP it was time to compare 2GB and 4GB memory configurations in Windows Vista.
