@LaurentG

I must agree with "hammerdown". Last release with low CPU usage was 4.1.6 and 4.1.7 with 0-4% CPU usage. Since version 4.1.8 with same minimal settings are there periodically 8-50% CPU usage + Drop outs on my AMD Athlon 1333 512MB with Geforce 2 MX400. Have somebody from the developers an idea what is differnt now?

I'm using AMD XP 2000 with an MSI Nvidia Geforce FX 5900XT with the latest drivers, and the latest WDM drivers, 2.26, from Nvidia's page. When I use DScaler 4.1.15 and earlier versions, the CPU usage, with all filters turned off, and deinterlace set to TomsMoComp (even tried em all) the cpu usage is between 90 and 100%. Is this due to Nvidia's WDM drivers? Didn't think it would take the whole CPU to get a picture from my satellite (Svideo). Did anyone else experience this before? Any possible solutions? Any help would be greatly appreciated. Thanks.

Have here only AMD users problems with CPU usage?

I am having the same problem. ANY of the deinterlacing methods, after no flipping of channels for around 5-10 seconds, the process load will go from 2-12% (depending on the selected method) and grow to 45-50% (I have dual core so one core becomes fully loaded) within seconds. Once I change the channel, it drops down to 2-12% but within another 5-10 seconds it starts climbing back to 45-50%, wasting electricity and producing more heat. Only the blended clip method is the one that randomly drops back down for a while or climbs back up to 50, the rest of the methods stay 50 until I change the channel. Are the developers aware or do we all have a system configuration problem all related? All my drivers, BIOS's and so on are up to date. My system is easily qualified to run a TV program.

I've changed some values from dscaler.ini and now Dscaler is using less CPU (around 16 and 30%). Before it was getting 90% of CPU from my P4 3.0Gz HT. It's loosing some frames, but I don't care.

ProcessorSpeed=0
TradeOff=0
FullCpu=0
SleepInterval=6
bHurryWhenLate=1

The SleepInterval is the main key to use less CPU. When the value is higher than 10 milliseconds, Dscaller loose too much frames.

sorry my bad english...

I got only 6% CPU usage while watching.
