Sapphire Radeon HD 5850 Toxic 2GB Review

Testing:

What would testing be if you did not show both sides of the fence? In this test, PhysX was set to low, while leaving the remaining settings intact. You have seen time and again where the ATI cards suffer when PhysX is enabled. Mirror's Edge and Cryostasis are two prime examples. Darkest of Days is no different. What happens in this test shows that, although the game can be played by cards from the red team, the video effects and quality are diminished.

Game Settings:

• 4x Anti-Aliasing
• 16x Anisotrophic Filtering
• PhysX: Low
• Ambient Occlusion: On
• Quality: High
• Resolution: 1280x1024 - 2560x1600

Higher is Better

Darkest of Days is the first game to show a drop in performance when compared to the 1GB edition. Overclocking does yield a benefit in all four resolutions delivering performance close to or higher than  the level of the HD 5870.
