Tilføjelse til #5. We tested, and re-tested this to be sure what we are seeing was correct. The NVIDIA GeForce GTX 780 Ti 3GB video card suffers from performance issues that directly relate to texture loading. As we entered new scenes in the game, or were entering or swinging the camera around to new areas that had to load the scene and textures there were at times severe drops in performance as the textures loaded in. This happened indoors and while we were driving in the open world city. It can clearly be seen on the graph.
The Radeon R9 290X GPU based video card has more VRAM on board, 4GB, and this seems to have given a different and better gameplay experience in this game. None of the performance drops experienced with the GTX 780 Ti happen on the Radeon R9 290X GPU based video card. The extra VRAM has made it so that performance is smooth with no discernible lag or stuttering while loading new scenes or new textures as we move about the game. This can really be felt as you drive through the city in the open world, it is much smoother on the Radeon R9 290X GPU based video card.
Due to those performance drops the XFX R9 290X DD video card is faster in minimum and average framerates and produces the best gameplay experience at "Ultra" texture settings. While the "performance" is playable on the GTX 780 Ti, the experience is choppy and inconsistent.
Ultra textures demand a lot of VRAM, and while 3GB may be required to allow it to work, it is certainly not the optimal solution for the smoothest performance. http://www.hardocp.com/article...
