My HIS 4870 is running choppy like. Is something with the card?

[Messerschmitt]

Basically the card doesn't run smooth in games, and when environments move you can see them go faster, then slower, then faster, then slower, etc.

I'm running now the Catalyst 8.10. When I tried the 8.12 TF2 became quite unplayable as the FPS was even lower in open than on my 8600 GTS, and choppy there too, as in the right word, not faster and slower, but choppy frames.

I have used driver sweeper and driver cleaner when un-installing drivers, and all.

Here are the videos that show what i'm talking about.

And not really speeding up, but more choppy in the right sense.

From your other post on forum, you switched from a NV card to ATI. Well, that is not as bad as switching motherboards, but still Windows sometimes freaks out because of this, you will probably have to do a reinstall.

Some one on another forum said that it might be because of my nmedia 500W power supply. Can a bad power supply exhibit these "slow,fast,slow,fast" symptoms with games that require the video card to spit out more power?

[Messerschmitt]

I fixed my issue. A full format straighten everything up. It seems that forgeting to uninstall the nvidia drivers first before isntalling the catalyst screwed everything up. Even after I ran driver cleaners and everything.

However I have also decided to change my nmedia PSU as well, even tho it works good with it. I just don't want to get stressed too much with my shiny new ATI and a new WD black 640 and blow up, possibly taking my toys with it too. And next time I will make sure I won't skimp on a PSU as I don't skimp on ram, videocard, HDD brand (quite virgin with ATI so not sure how good this HIS brand is)

... quite virgin with ATI so not sure how good this HIS brand is.

It´s a well build brand, using mostly the ATI design for board layout and with that the stock ATI cooler. Compared with others I can´t say much about HIS, I usely go with Sapphire (Who only makes ATI based cards).
