The thing about performance issues is they slowly become less relevant as time passes. Back in 2006 you needed a lot of grunt to get the most out of CoH. If you were lucky enough to have a $500 x1900 you could max the game at a whopping 40fps at 1024x768. I'm sure plenty of people complained they couldn't run high settings above 10fps on their favourite 6600gt even though it played CS flawlessly. Fast forward 8 years and we still have people who talk about how good CoH looks and nobody cares about performance in the slightest.
Having said that, if they can squeeze more out at the bottom end without impacting the experience for higher-end users that would be a very good thing in terms of popularity right now, today. Many of us are completely happy with the performance on high settings considering how stunning the game looks. But a common complaint is that low end computers are always bottlenecked regardless of how much you push down the settings.
Dude but COH2 looks average for what it demands. Back in 06 there was no RTS looking so good as vCoh which still kicks for the age it has. CoH had great demands but it had the best graphics also, fast forward 8 years and you get an average game with FX that are inferior to vCOh but you need a NASA computer for it.
