AMD Radeon HD 7800 - Query on Specs

I used an AMD Radeon HD 7800 Graphics Card when I built a new PC in 2013. Just after Christmas I installed a train simulator game (Train Sim World) and in less that 2 weeks of use I got an error message. I logged this with Dovetail Games (Steam) support who requested a copy of my DxDiag file. They then replied to say that my graphics card did not meet the minimum specs for the game which is shown on their website as 2Gb.  When I looked at my DxDiag file it seems to indicate that my AMD Radeon HD 7800 actually does meet the minimum specs, with 3 values shown one being 4Gb and the other two at 2Gb. I've copied the specs for the game and from my Graphics card so would appreciate if someone could confirm that my card meets the minimum specs, as I'm not sure which of the three different memory is the one related to VRAM. One of the conditions of a refund is that my PC meets the published game specifications.


Another issue that Dovetail Games support mentions is that I'm using an old driver, which is true . However I am intentionally using an old driver for a particular reason which I am going to do as a separate post as it is a different issue.


What TSW needs:

  • Graphics: nVidia GeForce GTX 750 Ti or AMD Radeon R9 270 with 2GB VRAM or more (nVidia GeForce GTX 970 or AMD Radeon RX 480 with 4GB VRAM or more recommended)


My AMD Card, per DxDiag:
