2077      * certain family differ in clockspeeds, the amount of video memory and the
2078      * number of shader pipelines.
2079      *
2080      * A Direct3D device object contains the PCI id (vendor + device) of the
2081      * videocard which is used for rendering. Various applications use this
2082      * information to get a rough estimation of the features of the card and
2083      * some might use it for enabling 3d effects only on certain types of
2084      * videocards. In some cases games might even use it to work around bugs
2085      * which happen on certain videocards/driver combinations. The problem is
2086      * that OpenGL only exposes a rendering string containing the name of the
2087      * videocard and not the PCI id.
2088      *
2089      * Various games depend on the PCI id, so somehow we need to provide one.
2090      * A simple option is to parse the renderer string and translate this to
2091      * the right PCI id. This is a lot of work because there are more than 200
2092      * GPUs just for Nvidia. Various cards share the same renderer string, so
2093      * the amount of code might be 'small' but there are quite a number of
2094      * exceptions which would make this a pain to maintain. Another way would
2095      * be to query the PCI id from the operating system (assuming this is the
2096      * videocard which is used for rendering which is not always the case).
2097      * This would work but it is not very portable. Second it would not work
2098      * well in, let's say, a remote X situation in which the amount of 3d
2099      * features which can be used is limited.
2100      *
2101      * As said most games only use the PCI id to get an indication of the
2102      * capabilities of the card. It doesn't really matter if the given id is
2103      * the correct one if we return the id of a card with similar 3d features.
2104      *
2105      * The code below checks the OpenGL capabilities of a videocard and matches
2106      * that to a certain level of Direct3D functionality. Once a card passes
2107      * the Direct3D9 check, we know that the card (in case of Nvidia) is at
2108      * least a GeforceFX. To give a better estimate we do a basic check on the
2109      * renderer string but if that won't pass we return a default card. This
2110      * way is better than maintaining a full card database as even without a
2111      * full database we can return a card with similar features. Second the
2112      * size of the database can be made quite small because when you know what
2113      * type of 3d functionality a card has, you know to which GPU family the
2114      * GPU must belong. Because of this you only have to check a small part of
2115      * the renderer string to distinguishes between different models from that
2116      * family.
2117      *
2118      * The code also selects a default amount of video memory which we will
2119      * use for an estimation of the amount of free texture memory. In case of
2120      * real D3D the amount of texture memory includes video memory and system
2121      * memory (to be specific AGP memory or in case of PCIE TurboCache /
2122      * HyperMemory). We don't know how much system memory can be addressed by
2123      * the system but we can make a reasonable estimation about the amount of
2124      * video memory. If the value is slightly wrong it doesn't matter as we
2125      * didn't include AGP-like memory which makes the amount of addressable
2126      * memory higher and second OpenGL isn't that critical it moves to system
2127      * memory behind our backs if really needed. Note that the amount of video
2128      * memory can be overruled using a registry setting. */
