Resource limiters:
These help prevent Growler Guncam from overusing resources on the computer that could end up hurting performance.

Number of frames in buffer:
This is the maximum number of frames that Growler Guncam will store in RAM. Growler Guncam attempts to write video to disk (in a temporary file)as quick as it captures it, but with certain settings and/or systems - Guncam can capture data faster than the hard-drive can write. This causes data to become buffered in RAM. If this situation continues long enough, Guncam will use the entire available RAM, and that can cause performance problems.

Max File size:
Growler Guncam now supports greater than 4 gigabyte file sizes if the file system allows for it (FAT32 will not)But just because one can have a 500 gigabyte file, doesn't mean one wants one. To limit the amount of disk space Growler Guncam will use, enter in the max file size in megabytes here.

Enable 'Record on' overlay:
If enabled, this will cause a green square to appear in the upper left hand corner when capture is underway. It does not work in 'exclusive mode' games. If enabling this causes problems, please email

Stop Capture Triggers:
These checkboxes make it so one can stop any recording if common 'exit' keys are pressed. These keys are 'alt-tab', 'alt-F4', and 'esc'.

OpenGL, Direct3D9 and DirectDraw enhancements:
If checked, this will help remove flickering images. It will also help performance when a game's frame-rate drops below the video capture rate, so it is very useful in making sure a game sustains an adequate frame-rate. It does not work in all games. If it does work in a game, it will cause a 'ding' to sound when the game begins. If this feature causes problems, please email . If you are experiencing problems with Guncam and Punkbuster (you should NOT)try disabling this feature. If doing that works, email us immediately!

Capture Method:
DirectX capture is the faster capture, but in some circumstances GDI may capture better. If Direct X capture is selected, and Guncam fails to capture in Direct X mode, it will default to GDI capture. If the 'enhancements' are working, Guncam will be using DirectX.

Real time compression:
The real time compression option allows a user to capture video for extended periods of time without quickly overrunning the available disk space. There are two types of compression: high compression and fast compression.

High compression uses a quality value from 1 to 100. A higher number will result in a better looking video, but the drawback is that the higher quality video takes up more disk space. This compression method can take up a significant amount of CPU time and can reduce in-game frame rate. It is advisable that one uses a small video size when capturing with high compression.

Fast Compression Version 1 compresses the video roughly 5X to 8X in real time with little performance hit over regular uncompressed capture.

Fast Compression Version 2 compresses the video roughly 6X to 9X in real time with little performance hit over regular uncompressed capture. It has less of a performance hit than Version 1.

No compression. This copies the video straight to disk with no compression. This can result in a high-quality capture, but if the video size of capture frame rate is too high, it might capture data at a rate higher than the data can be written to disk.

THIS IS NOT RECOMMENDED. You may hear people speak on web forums how "XYZ is fast at video capture  because it doesn't compress." They're wrong. For one, XYZ compresses ( trust me, it does), they just don't know it. For two, no compression means you can't write to disk fast enough, which means your video fills all available memory quickly, which means the OS starts putting operational memory into the swap file, and that's when all hell breaks lose. I don't even know why I'm giving you this option.
