HardOCP has published a gameplay performance and image quality test of F.E.A.R. 2: Project Origin. You can check it out over here.
We are using seven video cards in this evaluation. From AMD, we have a Radeon HD 4870 X2 with 1GB of GDDR5 memory per GPU, a Radeon HD 4870 with 1GB of GDDR5, a Radeon HD 4870 with 512MB of GDDR5, and a Radeon HD 4850 with 512MB of GDDR3 memory. NVIDIA is represented by a GeForce GTX 285 with 1GB of GDDR3, a GeForce GTX 280 also with 1GB of GDDR3, and a GeForce GTX 260 (216 Core) with 896MB of GDDR3 memory. Unfortunately, due to the timing of this article and the severe lack of GeForce GTX 295 stock currently, we were not able to include the GeForce GTX 295 in this evaluation. We will represent F.E.A.R. 2 gameplay on the GTX 295 in future reviews of GTX 295 video cards.
If you're gaming on a 20" or smaller display the reporter recommends the ATI Radeon HD 4850, for 24" gamers the Radeon HD 4870 512MB or 1GB is a good choice and if you're lucky enough to have a 30" LCD display the GeForce GTX 285 is the recommended card.
