Bit Tech has taken a look at the Company of Heroes DirectX 10 patch.
" More importantly, we must give kudos to Relic for taking the time to give Company of Heroes fans a graphical update for free. It's incredibly hard to take a DirectX 9.0 game and successfully port it to DirectX 10 - there are undoubtedly a lot of features that the developers had to turn down because they would have required a complete engine overhaul. Given the amount of time we could imagine that taking, it wasn't worth it when there is essentially no financial return on the developer's time. From what we've been told though, there will be some more pronounced DirectX 10 effects in the expansion pack which is coming later this year."
