After quite a long break over the Summer, I recently started to use my Phoenix flight sim again. Checking their site I noticed I was quite a few releases behind, so decided to download the updates and upgrade my installation.
Although the installs all went OK, the results were very disappointing, with dodgy shadows and very clunky slow graphics. As the latest release was Beta, I decided to send off an email to the support address, not really expecting much from what is surely a pretty niche product. To my pleasant surprise, I got an almost instant response, and after a fairly lengthly, but rapid, exchange of emails, my issues were resolved with an upgrade to my Nvidia drivers and also Directx.
