Vista and DirectX 10

1 minute read

This weekend I took some time out to reformat my development computer in preparation for Windows Vista. I used Vista before but switched back to XP x64 in less than a week’s time. But heck, after a year and a Service Pack, I was willing to take the chance with Vista.

I wanted to take advantage of the DirectX 10 features Vista exposes since they’re not available on XP but was kind of disappointed with the performance of the API in Vista. It seems to me that the samples provided in the DirectX SDK simply run much slower than on XP.

Granted, I bought the most budget oriented GPU that supports DX10 (Geforce 8500GT 512VRAM) but that was simply because of the reason that I want my projects to be able to run on the lowest budget hardware possible while still being able to access DX10-like features. Dell, in fact, offers the 8400 on their laptops and budget desktop PCs, which is a fair share of the market and should be targeted.

Vista itself seems pretty solid so far; it certainly responds better than a year ago and supports all of my hardware and development tools (VS 2008, AQTime, Intel C++ compiler, etc). The big test will be OpenGL: Will it also have performance drops or stay the same? I’ll see tonight.
