Is there any particular reason that the CUDA miner would only perform at maximum khash/s if its CLI status window were the foreground window? I'm seeing consistent drops from 16000khash/s to 6000-9000 khash/s when the window is not in the foreground, even if absolutely nothing is happening in whatever window is the foreground (even away from the computer).

This seems to be a new bug in the 1/28 binaries. I'm seeing it too. The previous version did not exhibit this behavior.

Currently, if my RPC Miner is in the foreground, it does its usual ~39M. As soon as I minimize, or even just click away, it drops straight down to ~4M.

I'm on Windows 7 (64 bit), GeForce GTX 260, 12GB of system memory, i7-920 CPU.

I'm running the CUDA miner, with no special parameters. But, just in case it matters, this is how I launch the software (via batch file):

Code:

@echo off

echo Launching Bitcoin. Please wait ...

rem start bitcoin
cd "C:\Program Files (x86)\Bitcoin"
start /min /low bitcoin.exe -gen -server

rem wait ten seconds
ping 127.0.0.1 -n 10 -w 1000 > nul

rem start rpc miner
cd "C:\Program Files (x86)\Bitcoin\rpcminer"
start "RPC Miner" /min /low rpcminer-cuda.exe -gpu -url=http://127.0.0.1:8332/ -user=XXX -password=XXX

I suspect it has to do with the lower CPU utilization fix. Which, by the way, is working very well. But perhaps this is why???

Thanks,
