My software of choice was HyperSnap-DX, but as soon as FRAPS appeared, I switched to this tiny and fast app.
This was also the first app that showed up real differences between AGP and PCIe graphics cards, since with PCIe cards we could capture files at full resolution, something that I could never do with 66MB/s upload on my 6800Ultra.
A highly useful feature was also the fact that Fraps is a benchmarking utility that captures real number of frames rendered per game, which helped reviewers a lot.
But, as Vista came out with the DirectX 10 API, Fraps stopped working, since it had some difficulties with overlay and measuring the number of frames. Now, with the release of 2.9.0, all problems are resolved and the new version of Fraps fully supports benchmarking and screen grabbing under Windows Vista and DX10 games. It also sports support for Vista's new audio subsystem, so videos can be recorded as well.
Support for multi-threaded games is fixed and owners of Logitech G15 keyboard and Vista can see frame rate counter and graph running in full speed.
If you use Fraps, head over to the site here. If you are not using Fraps, you might want to check it out. The free version is good and does not bug you with please register marks. It is made by an indie developer, so if you want to support the lad, your thing. ยต
