1920x1200 – High/Medium/Low
At 1920x1200 things really start to become taxing on our graphics card lineup. With the high quality settings in use, the Radeon HD 5870 was the only graphics card that had the goods. A single Radeon HD 5870 averaged 69fps, while a pair of them in Crossfire managed an impressive 100fps.
The graphics cards that squeezed into our acceptable level of performance lines were the Radeon HD 5850, 5830, 4890 and GeForce GTX 285, GTX 275. Then it was the Radeon HD 4870, 5770, 5750 and GeForce GTX 260 that just scraped by with playable performance.
That said, those using these graphics cards at 1920x1200 using the high quality settings with 2xAA/4xAF will experience stuttery gameplay from time to time. Everything below the red line was no good at this resolution.
The medium quality settings at 1920x1200 opened up the number of graphics cards that could deliver acceptable performance. The GeForce GTX 285 was promoted into the perfectly playable category, placing it alongside the Radeon HD 5870.
There were 7 graphics cards tested that delivered acceptable levels of performance and they are situated under the green line and above the yellow line. There is just a pair of Nvidia based graphics cards here and five AMD graphics cards.
By using the low quality settings, which is a far from desirable option, the Radeon HD 5670 and GeForce 9600 GT/GT 240 just scraped by with playable performance, though lag will be noticed. The GeForce 9800 GT and Radeon HD 4850/5750/5770 were far less likely to run into lag spikes with frame rates in the 50fps range.
For lag-free gameplay using low-quality settings at 1920x1200, gamers will require a Radeon HD 4770 or faster. Sitting above the Radeon HD 4770 we have 8 graphics cards, all of which averaged 60+ fps for stutter-free gameplay.
