Recently started converting a laptop into a media pc after the screen broke.
it's a somewhat mid level gaming laptop running windows 7 with stats:
quad core intel core-i7 clocked at 2ghz (4 real, 8 virtual)
Discrete nvidia GeForce GT 555 M
and integrated Intel HD 3000
6 Gb DDR5 RAM
I've been adding emulator launchers to XBMC and they've all worked perfectly until i got to the ps2. I've got pcsx2 up and running properly or what i'm pretty sure is properly. i've read many of the guides and lurked to make sure i know what everything does and i've had the same problem in nearly every game i've played.
the games will run fine at 60 fps for a little while but then every few seconds for a couple seconds the fps will drop to around 30-40 and then return to 60 fps a couple of seconds later. this repeats and makes the games pretty unplayble. it's not a variable thing where the game will run somewhere between 40 and 60 fps but the EE and GS cores will jump up from 50-60% to nearly 100% load on both engines and the fps will drop.
i've done some profiling of it and the load on the gfx card never goes above 20% and my cpu never gets above around 45 % so i'm pretty sure they aren't being taxed to heavily.
Also this problem seems to be independent of resolution as it happens at both native resolution, 2x and 3x.
WHAT I'VE TRIED:
the newest stable build pf pcsx2(1.0) and the latest svn revision(r5730)
i've made sure that pcsx2 is using my discrete card(geforce GT 555M)
made sure i'm using the highest performance modes in my power management
checked for speed step settings in my bios
all manner of speedhacks
skipdraw up to 20
8-bit textures both on and off
ee-timing hack(for when all else fails)
windows classic theme
direct x 9 and 11 in hardware as well as software
graphics plugins SSE 2 through 4.1
agressive CRC and disable CRC (not at the same time)
Guesses:
the 555m in this laptop looks like it shares its vram with the integrated card but the load for both of them has never been close to the max(1024mb)
the times when it's running at 60fps are the outliers and theres some sort of turbo coming into effect that i don't know about(seems unlikely due to simmilar issues at higher resolutions)
there's some setting or issue with pcsx2 that i don't know about causing this problem on this specific system.(seems likely as i've been able to run pcsx2 without this problem on both more and less powerful machines)
i would post a screenshot of my config but given how many permutations i've tried it seems pretty useless.
is there anything i'm missing?
