I use to play games like FF XII(60 fps) , Unlimited ninja 5(50 fps/pal) or 4 , couple other games and even god of war with minor issues , with full speed.
And then .....
Today I wanna play some battle in UN 5. And something goes wrong. I got like 30 fps with all games ( monster hunter still goes with 60 FPS) , on god of war I got 12 fps ! I don't know what happend I tried to restore the system to the last restore point but it did not helped. Than I notice that my cps usage is pretty low like 40-60 % , before was like 80+ % and games went good.
(I do not install any new programs , only my mcaffe anti vir was updated , nothing more)
Can some one help me ? What can cause this issue ? ( I set full performance or power saving mode and there is no great difference almost none).
ps: I played some game on desmume 9.7 ver mean while last pcsx2 plays (may be this ? )
my guess thermal throttle check your temperature !
Nah it's not this. My laptop isn't even warm. Earlier when my laptop went hot I got some minor fps drops for only couple sec.

you com cannot for ps2 game cost need at least core i5 or i7 to run the game.
if your com is intel centrino core 2 duo that type ko confirm cannot
centrino is the lousy cpu in the world
for laptop you need to go setting change to full performance not balance performance setting laptop is abit troublesome than desktop
this is ps2 machine spec
ps2 machine hardware spec
CPU: 64-bit "Emotion Engine" clocked at 294.912 MHz (299 MHz on newer versions), 10.5 million transistors
System memory: 32 MB Direct Rambus or RDRAM
Memory bus Bandwidth: 3.2 gigabytes per second
Main processor: MIPS R5900 CPU core, 64-bit, little endian (mipsel).
Coprocessor: FPU (Floating Point Multiply Accumulator × 1, Floating Point Divider × 1)
Vector Units: VU0 and VU1 (Floating Point Multiply Accumulator × 9, Floating Point Divider × 1), 32-bit, at 150 MHz.
VU0 typically used for polygon transformations optionally (under parallel or serial connection), physics and other gameplay based things
VU1 typically used for polygon transformations, lighting and other visual based calculations (Texture matrix able for 2 coordinates (UV/ST))
Parallel: Results of VU0/FPU sent as another display list via MFIFO (E.G. complex characters/vehichles/etc.)
Serial: Results of VU0/FPU sent to VU1 (via 3 methods) and can act as an optional geometry pre-processor that does all base work to update the scene every frame (E.G. camera, perspective, boning and laws of movement such as animations or physics) 
Floating Point Performance: 6.2 gigaFLOPS (single precision 32-bit floating point)
FPU 0.64 gigaFLOPS
VU0 2.44 gigaFLOPS
VU1 3.08 gigaFLOPS (with Internal 0.64 gigaFLOPS EFU)
Tri-Strip Geometric transformation (VU0+VU1): 150 million polygons per second
3D CG Geometric transformation with raw 3D perspective operations (VU0+VU1): 66-80+ million polygons per second
3D CG Geometric transformations at peak bones/movements/effects (textures)/lights (VU0+VU1, parallel or series): 15–20 million polygons per second
Actual real-world polygons (per frame):500-650k at 30fps, 250-325k at 60fps
Compressed Image Decoder: MPEG-2
I/O Processor interconnection: Remote Procedure Call over a serial link, DMA controller for bulk transfer
Cache memory: Instruction: 16 KB, Data: 8 KB + 16 KB (ScrP)
Graphics processing unit: "Graphics Synthesizer" clocked at 147 MHz
Pixel pipelines: 16
Video output resolution: variable from 256x224 to 1280x1024 pixels
4 MB Embedded DRAM video memory bandwidth at 48 gigabytes per second (main system 32 MB can be dedicated into VRAM for off-screen materials)
Texture buffer bandwidth: 9.6 GB/s
Frame buffer bandwidth: 38.4 GB/s
DRAM Bus width: 2560-bit (composed of three independent buses: 1024-bit write, 1024-bit read, 512-bit read/write)
Pixel configuration: RGB: Alpha:Z Buffer (24:8, 15:1 for RGB, 16, 24, or 32-bit Z buffer)
Dedicated connection to: Main CPU and VU1
Overall pixel fillrate: 16x147 = 2.352 Gpixel/s (rounded to 2.4 Gpixel/s)
Pixel fillrate: with no texture, flat shaded 2.4 (75,000,000 32pixel raster triangles)
Pixel fillrate: with 1 full texture (Diffuse Map), Gouraud shaded 1.2 (37,750,000 32-bit pixel raster triangles)
Pixel fillrate: with 2 full textures (Diffuse map + specular or alpha or other), Gouraud shaded 0.6 (18,750,000 32-bit pixel raster triangles)
GS effects: AAx2 (poly sorting required), Bilinear, Trilinear, Multi-pass, Palletizing (4-bit = 6:1 ratio, 8-bit = 3:1)
Multi-pass rendering ability
Four passes = 300 Mpixel/s (300 Mpixels/s divided by 32 pixels = 9,375,000 triangles/s lost every four passes)
Audio: "SPU1+SPU2" (SPU1 is actually the CPU clocked at 8 MHz)
Sound Memory: 2 MB
Number of voices: 48 hardware channels of ADPCM on SPU2 plus software-mixed channels
Sampling Frequency: 44.1 kHz or 48 kHz (selectable)
Output: Dolby Digital 5.1 Surround sound, DTS (Full motion video only), later games achieved analog 5.1 surround during gameplay through Dolby Pro Logic II
I/O Memory: 2 MB
CPU Core: Original PlayStation CPU (MIPS R3000A clocked at 33.8688 MHz or 37.5 MHz)
Automatically underclocked to 33.8688 MHz to achieve hardware backwards compatibility with original PlayStation format games.

Did U even read what I said. I could PLAY ps2 games, with minor problems in games like god of war. Rest games which I mentioned , went at 60/50 FPS depend of their region. ( of course I got some fps drops but ,it was like couple sec) So I don't get it ,why did U post Ur theory that, my laptop can not run ps2 games.
PS: It's confusing. Today I went my pcsx2 and I can play games normal. I don't get it. So topic can turn off.
