I have an HP Dv7 laptop. I upgraded from vista home, to win7 home. Everything worked great except that anytime I tried to play a video from youtube or anywhere else, or play CoH, or access a website that used Adobe Flash, I would crash. So... after hours and hours of testing, I finally figured out it was my vid card drivers.
I had to completely uninstall my video card drivers... and re-install them from HP's website. Everything works great now. My vid card is an ATI Radeon Mobility 4500 series.
Had this problem earlier in the night as well, after upgrading from Vista 64 ultimate to W7 64 Ultimate. I used TweakCoH (Thanks Darkfaith) and lowered everything. I was able to load into the game, and realized that, even on the lowest settings, I was getting about 16 FPS. Updated my drivers, all is good.
Drivers for a few of my things seemed a little buggy after installing W7. Check those first, my .02
Win 7 comes with default drivers for a lot of cards, but those defaults are usually missing things that CoH needs to run. For example, it'll automatically install the core drivers for my nVidia 9800 GTX+, but those drivers are an absolute minimum and don't include things like the nVidia control panel. The drivers that Win 7 installs are, by default, the most current that nVidia has submitted to MS (at the moment they would be the 191.07 drivers), but it's missing just enough from the nVidia downloaded drivers that it won't run City.
As for Direct X, Win 7 comes with Direct X (either 10 or 11, can't remember which at the moment), so it'll run City without installing anything more in that regard, but the version that's installed has certain things disabled by default, so it won't run Aion without either a manual change of those settings, or the Direct X 9 install (which activates the settings that are disabled for you, more or less).
A software such as nVidia Control Panel is rather essential, though.
Honestly, I stick with Windows' default drivers for mostly every device other than my graphics card. It keeps my PC from being bloated by unneeded driver softwares. A software such as nVidia Control Panel is rather essential, though. |
