Opti '82C264'
The Opti 82C264 is a card I haven't seen in abundance. Perhaps a good thing since it's performance in DOS isn't that good. In Doom it's far behind and even cards like Trident 9440 supersede the Opti-based card. Generally any S3-card is a far better option; especially when running in SVGA mode.
The card looks identical to an A-Trend ATC2045. If it were an A-Trend card you could identify it by it's AQA-sticker and the ATC2045 marking on the PCB. > Read more
