Numerous problems in Eyefinity gaming with Crossfire setups
AMD video cards in Crossfire seem to have with displaying games on different monitors problems. The cards show off and display frames frames together. According to AMD is caused by a problem in the synchronization of the frames.
A variation in frame times may stuttering image concerns, while the measured framerate there not points . By measuring the time frame has previously also been demonstrated that in Crossfire exhibits micro stuttering occurs. In addition, a frame is relatively long in the making, while the next frame is done extremely quickly, which also leads to a stuttering view. In response to the problems with micro stuttering has the AMD 13.8 beta driver released, in which the ‘frame pacing’ option is added. For games that use DirectX 10 or 11 at resolutions of up to 2560×1440 pixels were thus solved the problems with frame times.
A survey of PC Perspective, which also previously examined frame times, has shown that in combination with monitors in Eyefinity mode several new problems in Crossfire setups. Instead of micro stuttering seem to disappear. Entire frames In Bioshock Infinite, there appeared to fall to the frame. Away a frame This ensures on the one hand that the game runs less smooth and secondly, it prevents software like Fraps, which the frames not shown it detects twice as high framerate reports.
Interleaving in Grid 2
In addition to the disappearance of frames is also shown that, frames are displayed by each other. In the test setup each frame gets a color with it. From image above shows that there are pieces of a ‘yellow’ frame by ‘pink’ frame back down. This creates distortions in the image, the stripes on the front foot American flag is not right. By the disruption
Interleaving in Bioshock
In several games the interleaving also proves ‘neat’ to be horizontal. Tears are created which on the one side of the display vertical pixels occupy more than on the other side, as in Bioshock in the illustration above.
The problem is not only relevant for gamers who want to play games on different monitors but also for users of a screen with 4K resolution. Although screens with this resolution using a display port cable for image transfer, but the image is made up of two streams of 1920×2160 pixels, using the same cable. Poor software uses a 4K screen so an Eyefinity setup.
In response to the publication of PC Perspective AMD has announced work on solving the problems hard. AMD would like to make. Known solution already, in the very near future ‘Viewing:-154
