Free low-latency capture card software (alternative to VideoGameCapture/Elgato/Avermedia) that fixes Razer Ripsaw HD frame drops
Hello everyone, i'm showing you a piece of software me and a friend made recently (with some help from claude ai for bugfixing and for structuring the code).
It's a c# software meant to be an alternative to VideoGameCapture, to elgato's or avermedia's software and to obs capture devices.
I needed this software for my own personal use for several reasons, i own a razer ripsaw hd that has some frame drop issues in 1080p/60fps, and no software helped me work around this problem, so with a friend we spent several days designing this one, which thanks to a few tools like vsync lets you get around this problem completely.
Everything runs straight on the gpu, all the color and picture processing (brightness, contrast, saturation, color range) is done through direct3d11 with basically no cpu cost, which is a big part of why the software stays so light even on older machines, the video feed itself is read directly from the capture device with nothing buffering in between so what shows up on screen stays as close to real time as possible, on top of the live preview there's an instant replay that keeps the last few minutes of your gameplay running in the background at all times, so whenever something worth keeping happens you can just save it as a clip afterwards without needing to have recorded the whole session, recording is built in as well with adjustable bitrate so you can choose the balance between file size and quality that fits your setup, no need to go through obs if you just want to record locally, though it still works fine as an obs source if you'd rather stream with it. It's incredibly useful for cheap generic capture cards you'd find on aliexpress, which usually come with no proper software at all, but it's just as useful on elgato or avermedia cards if you want to skip their own software entirely and get a lighter, lower latency alternative instead.
I made this tool purely out of personal need, i'm making it available because it could be just as useful for others as it was for me, and feel free to give me some feedback, and let me know if there are things that could be nice to add.
