Hi!
I bought a Visiontek HD4870 1 week after its release, and the card has some very strange behaviors. In Crysis, Gears of War and Call of Duty 4, the game freezes for 3-7 seconds each time I turn around or when I look at very open spaces. I know the textures must be loaded but it was not that bad with my old 8800 GTS G80 (1 second lag max). However, when this stuttering isn't happening, the framerate is absolutely fantastic. Other games have no problems at all.
Here are my specs :
- E6750 @ 3.2Ghz
- HD4870
- OCZ StealthXtreme 600W
- 2Gb RAM 800Mhz
- Vista 32 bit
I tried reformatting, and I tested with every single driver available since 8.6 hotfix (even betas and custom drivers...). I also tried overclocking the card but it was actually worse. Temperature is not the problem. I ajusted the fan speed and my temps never go above 45C. My chipset drivers are up to date.
Any help/suggestions will be highly appreciated because right now, these games are unplayable.
Thank you and sorry for my bad English.
