Cheat Engine

anyone have a good idea on how to benchmark cheat engine 5.6? i wished ce included a counter that says it took x number of seconds/milliseconds to complete this search/scan (feature request, db? Razz

).

i'm thinking about building a new pc. one of the upcoming hexa core processors and maybe a new dx11 video card.

which would yield faster search results? amd or intel hexa cores? does ce spawn more threads when doing long searches (i.e. float or double). i wonder if ce could offload some of this to the video card because video card can do a better job/faster with floating point numbers.

i'm guessing these scans/searches rely heavily on cpu speed and ram speed the most. so the higher the clock speed and faster the ram the less time it takes to complete a scan.

so i think a good application to scan is microsoft calculator. since this application comes with windows, this would be identical on most user's machine. nevermind. the searches are done too fast with windows calc. Embarassed

anyone with a good suggestion? Wink

you could get the sourcecode and add in some code that checks how long it took to do a scan.
Also, first scan speed can be quite different from subsequent scans because the target process might have had memory paged to disk, but the memory scan will bring it back to active memory. So first scan will be slow(er) than the next ones

As for speed: It depends on diskspace, diskcache, cpu speed and cpu cache
The scanbuffer also makes a huge difference on the scan speed based on the amount of results you get.

So, besided the cpu, a faster harddisk is sometimes also a great benefit to scanning (which is why I think those standalone versions you run of usb sticks suck)

And yes, ce will spawn more threads depending on how many cpu's your system has (if hyperthreaded, it spawns the (total count divided by 2)+(total count divided by 4) )

i got the following result:

evaluated: 3092921 time: 64 (48122 /s )

this is on intel atom eee pc. intel atom n270 @ 1.6 ghz (1 core; 2 threads). Wink

ddr2 1 gb ram. windows 7 32bit.

i attached to opera browser with 15 tabs opened. i searched for 4-bytes, exact value of '1.' i ended up with 1,569,865 results. i add the 1st one. then right click and did the pointer scan with default options.

ok, I see your main bottleneck problem. Most games these day take up 1GB to 1.5GB of ram

cheat engine makes a copy of the game and scans that, and for the pointerscanner it generates a database of pointer of 1GB size as well.

so, when you're scanning, you're going to cause a lot of paging to and from disk

as for 1.6GHz, it's not much, but should be enough

As for the benchmark I usually just try the ce tutorial second step address with the option disabled to stop a path when a static has been found (my system with 5 threads tends to do 400000 /s after 60 sec)
