I’ve just downloaded and installed VCV Rack v1.1.6 under Windows 7, but I’m finding it very unresponsive. I don’t think it’s my hardware (I’m running Windows 7 Home Premium with SP 1 on an AMD Phenom II 810 64-bit quad processor rated at 2.6 GHz, with 8 GB of memory), but it keeps freezing (I get a “not responding” status in the title bar), and takes 20 to 30 seconds to recover. However, according to Windows Task Manager, total CPU usage doesn’t go above 20%.
It’s a very simple patch, basically the default that comes with VCV Rack when you install it, with only a few modules that I added myself (see attached screen print). There’s only one Audio 8 module in it (I’ve read that having more than one isn’t supported). Any idea what the problem might be?
The driver hasn’t been updated for Windows 7 since October 2013, it seems. According to the description on this web site, it supports OpenGL 3.3.
I’m using the Yamaha Steinberg USB ASIO driver that came with my audio interface (a Steinberg UR 22). It works fine with Pure Data, Max/MSP, Reaper, Audacity, and any other applications I have installed that use audio.
Seems it was the video driver after all. I re-installed the video driver and the problem went away. I wasn’t having this problem with any other applications, but I’m not sure which applications would use OpenGL. Thanks.
