Micomsoft 100% CPU bug fixed

So this bug has been circulating for awhile now and yesterday I discovered the solution. It's not by any means a good solution but it works perfectly. Originally I thought it was to do with what motherboard settings or configuration of C states you had.

You have to update to Windows 8 and all your troubles will be over. Upgrading from 7 was not as difficult as I thought it would be. I'd highly recommend doing this though if you want to have the perfect capture setup.

Update for April 2015

So I decided to look back at this and do some more investigation. If we look back at the Micomsoft driver page for v1.1.0.124, we will see this entry.

Windows8使用時にCPU使用率（合計）が98～100%と認識されてしまう問題に対策しました。

Roughly translated, it means they identified and fixed the bug, but only for Windows 8. I guess we can't really blame them since they probably only develop on latest operating systems.

To see if this was true, I downloaded the previous driver where the bug should have still been present (v1.1.0.122). The below screenshot shows the bug active.

I then uninstalled that driver, restarted the system and installed Micomsoft's latest driver. It has now been fixed (you can check the PS3 clock if you want). :P

So yeah, just make sure you are running Windows 8 and the latest drivers. Either from Micomsoft or the Yuan VidBlaster ones and you should be fine.

About Me

I'm just a guy from the UK that has a passion for video games and speedrunning (and of course capturing them). I originally started this blog because I wanted to share my knowledge and research I've gained over the years. Below is a brief history on my speedrunning and capture cards

I started speedrunning in mid 2006 with Resident Evil 4. Over the years I ran other games to world record level such as the Uncharted series, other Resident Evil titles, Heavy Rain and Clock Tower. I also enjoy glitch hunting video games. I was part of the team that found ways to skip 7 bosses in the original Metal Gear Solid game for PS1.

In early 2010, my first capture card was the Hauppauge HD PVR. Streaming with that device in 2010 was very difficult (basically screen region or nothing) so I moved onto the Blackmagic Intensity Pro in late 2010 since it was a DirectShow device. From then on I've added countless more capture cards to my collection from various companies such as AVerMedia, Blackmagic, Micomsoft, Dazzle and Elgato. I was also the first Western user to own and document the Micomsoft SC-512 capture card. It is now probably the most popular gaming capture card because of this.
