everyone, I just purchased and installed a HIS Radeon HD 4670 and I've been having some issues.
Im Running Win7 on a machine with an AMD Athlon 64 X2 3800 Processor, 3GB of RAM and 650W PSU. When I upgraded to Win7 i was using a ATI Radeon 1600 Pro. This card is not really fully supported by ATI in Win7 but it still did a decent job, i managed to run Aero fine and most of my games played without a problem. I was playing PES2010 and i had some lag in the in-game videos, celebrations etc, but gameplay ran very smooth.
I bought a HIS radeon HD 4670 hoping it would smooth things out but i am having problems with it. The in-game videos and celebrations, pre-game stuff all run great, smooth and beautiful. When gameplay starts though, it just lags tremendously, it is impossible to play. I have tried the Driver included in the installation CD, the driver which windows installs, and the latest drivers from both the HIS and ATI websites without any progress. I have bumped down the resolution of the game but i still get considerable lag. I just dont understand why the game would run fine with an old card not supported in Win7 but with a new one which is supported and double the memory would run slow.
@konakid getting another game doesnt really help since other games are suffering the same way. I used GPU-Z and it keeps telling me the GPU is running at 100% even when im not using anything like a game or movie. To tell you the truth i havent really played around with the settings in catalyst for 3D
I finally found a fix for the issue i was having. I found a forum where someone posted there was an issue with the Microsoft High Definition audio driver and these video cards. They recommended i disable the driver and restart the computer. I did so and now everything is running smooth, and I did not lose sound. All of the games i tested last night ran smoothly and way better than before.
