991 * features. In most cases GPUs from a certain family differ in clockspeeds, the amount of video memory and
992 * in case of the latest videocards in the number of pixel/vertex pipelines.
993 *
994 * A Direct3D device object contains the PCI id (vendor + device) of the videocard which is used for
995 * rendering. Various games use this information to get a rough estimation of the features of the card
996 * and some might use it for enabling 3d effects only on certain types of videocards. In some cases
997 * games might even use it to work around bugs which happen on certain videocards/driver combinations.
998 * The problem is that OpenGL only exposes a rendering string containing the name of the videocard and
999 * not the PCI id.
1000 *
1001 * Various games depend on the PCI id, so somehow we need to provide one. A simple option is to parse
1002 * the renderer string and translate this to the right PCI id. This is a lot of work because there are more
1003 * than 200 GPUs just for Nvidia. Various cards share the same renderer string, so the amount of code might
1004 * be 'small' but there are quite a number of exceptions which would make this a pain to maintain.
1005 * Another way would be to query the PCI id from the operating system (assuming this is the videocard which
1006 * is used for rendering which is not always the case). This would work but it is not very portable. Second
1007 * it would not work well in, let's say, a remote X situation in which the amount of 3d features which can be used
1008 * is limited.
1009 *
1010 * As said most games only use the PCI id to get an indication of the capabilities of the card.
1011 * It doesn't really matter if the given id is the correct one if we return the id of a card with
1012 * similar 3d features.
1013 *
1014 * The code below checks the OpenGL capabilities of a videocard and matches that to a certain level of
1015 * Direct3D functionality. Once a card passes the Direct3D9 check, we know that the card (in case of Nvidia)
1016 * is at least a GeforceFX. To give a better estimate we do a basic check on the renderer string but if that
1017 * won't pass we return a default card. This way is better than maintaining a full card database as even
1018 * without a full database we can return a card with similar features. Second the size of the database
1019 * can be made quite small because when you know what type of 3d functionality a card has, you know to which
1020 * GPU family the GPU must belong. Because of this you only have to check a small part of the renderer string
1021 * to distinguishes between different models from that family.
1022 *
1023 * The code also selects a default amount of video memory which we will use for an estimation of the amount
1024 * of free texture memory. In case of real D3D the amount of texture memory includes video memory and system
1025 * memory (to be specific AGP memory or in case of PCIE TurboCache/HyperMemory). We don't know how much
1026 * system memory can be addressed by the system but we can make a reasonable estimation about the amount of
1027 * video memory. If the value is slightly wrong it doesn't matter as we didn't include AGP-like memory which
1028 * makes the amount of addressable memory higher and second OpenGL isn't that critical it moves to system
1029 * memory behind our backs if really needed.
1030 * Note that the amount of video memory can be overruled using a registry setting.
1031 */
