FPHG available

[matt42s]

I have a couple of ideas for increasing fphg's performance - particularly for realtime mode but I wanted to bounce them off you before I got too far with implementing my hacks. The inner loops are solid but we're not taking advantage of the fact that most active hands turn up in the same region time after time. I added some tables to track the 'active' regions and scan them on every loop - the inactive regions get scanned once every 5-50 loops depending on delay settings, with delay at zero, I'm scanning twice as many 'active' regions and still picking up new hands in new regions when they do occur.
The other thing I saw is that readprocessmemory is kinda slow - tracking regions means we don't have to do it every cycle, but virtualqueryex is an absolute dog. I haven't tried it yet but I think storing the MBI's, trying readprocessmemory and only doing the virtualquery when rpm fails will be much quicker. Combining these, we'll end up with another outer, outerloop of 1 - 2 seconds where all 'previous' regions are rpm'd and queried only if rpm fails, all regions are then scanned, but inside this loop we rpm and scan the 'active' regions - maybe 5 to 10 times and we have a much better chance of catching all the data.
I'm already tracking the regions but am not doing it in a 'nice' way and my C has been rusty for a decade. eg
unsigned int RegionStart[80];
Pls let me know if you think I'm off base or am about to hit a wall.
I just read my post preview and it seems the coffee has got to me, sorry if its completely unreadable. I hope I got the idea across though.


just added the following couple lines to prove that virtualqueryex doens't HAVE to be called immediately before readprocessmem - we can store the MBI's and MOST of the time the page boundaries won't move (they do move around when opening and closing tables but that happens in macro time)
void* NextAddress = SI.lpMinimumApplicationAddress;
NextAddress = (void*)((DWORD)MBI.BaseAddress + (DWORD)MBI.RegionSize );
MEMORY_BASIC_INFORMATION MBI2;
DWORD Ret2 = VirtualQueryEx(hProcess,NextAddress,&MBI2,size of(MEMORY_BASIC_INFORMATION));
