I have an XFX 5850 Black Edition (minimally oc'd from factory). It works great for mining but my framerates in game suffer when mining. Is there any way to throttle back the aggression when a certain executable is launched or after a certain amount of cpu utilization (which could be indicative of a game loading)?

Thanks for any info.

Depending on which miner you use, you can set the aggressiveness to a lower value. e.g. on poclbm setting -f 100 would make the miner return control once every 10ms so you will get a theoretical upper limit of 100 fps, which should be sufficient for games.

So if my monitor's refresh rate is at 60 hz I would just need to set a flag to -f 60 to cap my framerate a 60 fps?

I'm wondering because I just added that flag and mining only dropped 10-20 Mhash/s. Seems like a very minimal impact on mining!

Thanks for the help. I'm still very new to mining so I get confused quite easily. Wink

Theoretically yes, but it would assume your game can complete its rendering tasks within the time. So I'd think a slightly higher cap would probably be better at ensuring you will get a steady 60fps. As usual, the best way to find out is to test different settings and share the discovery with us Cheesy

the only problem I have found is that often times the memory clock speeds that I run for mining dont jive with the gaming and therefore I end up having to adjust the clocks everytime I switch between gaming and bitmining. If only there was a bitminer app that also controlled gpu/memory clocks.

It would be hard for the app to tell if you're going to be gaming I would think. One alternative is to use saved profiles. I use Trixx to overclock and it allows up to 4 profiles per card. So it's just a matter of switching profiles before loading up the game.

Thats how I do it too. I have profiles set up for different stable overclocks for mining. If I want to play games, I just reset the clock speeds since it would otherwise crash the video card drivers upon starting a game.
