Hello i'm writing from Venezuela i know my English is not that good, but hope this wonderful forum can help me to achieve my goals, because to be honest as Venezuelan you guys don't imagine how bad the things are in my country right now the hyper-inflation etc,etc ... i barely can eat and i can't afford to buy a new pc :/ (this Government is the real hell...) so hope you guys can read the whole thread and help me

First off: I wanted to start by specifying what hardware specs do i have before finding a solution to my problem, i will be adding in the last of this comment the (DPC LATENCY Report)

PC SPECS:
-MotherBoard: H55M-e33(MS 7636)
-SSD: OCZ VERTEX 3 - (128 gb)
-Power Supply model: Thermaltake 775w ToughpowerXT
-Two sata hard-drive for storage - (150gb each one)
-Memory Model: Corsair Dominator Dual-Channel 4gb
-Processor Intel Core i3 530
-Nvidia Geforce 9600 gt 512 mb - (last drivers 341.96)
-OS Window 8.1 pro 64 bits
- have 3 stock fan-speed in left case cover, in the top of cpu, and front-panel bottom

CPU-Z CHARACTERISTICS:
CPU:
core speed: 2.9 ghz multiplier: 22 , bus-speed: 132, QPI: 2925
cache L1 Data: 2x32 Kbytes 8-way
cache L1 Inst: 2x32 Kbytes 4-way
level2: 2x256 Kbytes 8-way
level3: 4mbytes -16way

Memory:
Dram frequency: 665 mhz
Fsb:dram: 4:20
Cas#latency: 9.0 clocks
Ras# to cas delay (tRcd) 9 clocks
Ras# to precharge(tRp) 9 clocks

IDLE GPU-CPU temperatures:
CPU: 47-48 and it always up to 52 as maximum (100fan speed)
Gpu: idle is 63, fan speed 43% memory use 68 (monitoring with GPU-Z)
gpu can up like 80 as maximum in Diablo3 between 75-80 i read a forum wether people say thats normal with these Nvidia Card, i dont know to be honest...

Ok. let's start, I think i'm facing a problem with the dpc latency followed by the software (Dpc latency moon checker) beside that I'm that type of people that really like to have full optimized/responsive Pc when comes to play or just web-browsing on Internet, but to be honest i never have tried before to make here a Thread about my situation "maybe because of my poor English xd". but backing to the topic, I feel my like mi pc is less responsive.. dunno how to explain it well, but games are (choppy-sluggish) even at 100 frame rates per second, like (counter-strike 1.6) that game oh god.... i don't know what any else i can do to make that game performance well. it just feel not okay, just sluggish i feel in disadvantage like my game feels less than 100fps... mouse is not responsive at all, also I have notice that before install Nvidia Drivers seems like resolution generic 800x600 feels better like more snapy or responsive. And beside Counter strike 1.6 I feel Diablo-3 and Hearthstone games in General are not like optimized.

When running task manager I ensure that there are 0 background process running , only system and the classic-shell start menu. and it gave me (0% cpu, 15% memory consumption which i think is very good)
I also use the old classic Task manager windows 7 for (windows 8) to use less resources

Also I wanted to mention that I've follow aun user name r0ach from Overlock.net he is fantastic!! , I did follow hes whole guide in Overlock, about: "Turning bios settings for gaming and, how to properly do a good installation of Windows 8.1
source:
Gaming and mouse response BIOS optimization guide for modern PC hardware

I will add my H55M-e33(MS 7636 settings that i modify by following r0ach guide
I have last bios update and these are my settings:

On-Chip ata settings:
Pci Ide busmaster (i disable) it was on enable by default
On-Chip Sata Controller : Enable
Raid-mode AHCI (i have 2 hardrives for storage and one SSD so i pick AHCI)

Advance Bios Feature:
Pci latency timer default is 64, but it has 4 choices "32,64,96,128" (don't know which is better)
HPET (disable)
MP Tablet Version default is 1.1 or 1.4 default is 1.4 (don't know which is better)
IOAPIC Function: (enable) by default can also be disable so don't know which is better
Boot Up Num Lock ED (enable)

So thats pretty much all from my bios hope you guys can guidance me hehe ^^,
Some tweaks that i have apply to Windows:

-Removing hibernation Windows 8.1 through command prompt
-Disabling dynamic tick through command prompt
-Turning off page-file on SDD and putting page file in another Hard-drive
-By turning off all visual settings in performance tab leaving on only: the (Smooth Edges, thubnails on)
-By editing regedit Nagle’s Algorithm stuff like: TcpAckFrequency , TCPNoDelay, TcpDelAckTicks
source: that also works for windows 8.1
How to Tweak Windows 10 for Gaming - Back2Gaming

-By modifying regedit with this .reg file from:
Collection of Best Registry Tweaks to Speed Up Your Windows - AskVG
That also works for window 8.1 and make more snappy the right click function etc.etc


So guys sorry for writting alot but, as i said up-there I made a Clean installation of windows 8.1 pro following r0ach guide plus some minimal tweakings that I've mentioned. And i really don't feel games okay is just feels sluggish etc etc... I also cleaned my Pc components, added new thermal-paste silver 5, I vacuum my motherboard etc etc, and yeah don't know what any else i can do to play counter strike 1.6 more smooth, and others games like Hearthstone-diablo etc etc

i'm open to receive guidance,help,overclocking etc etc, i haven't overclocked in my life! i just remember i did once by using a software with my brother help, but it was like 8 years ago with an old pc , so hope you guy can help me and excuse me for my bad English, thanks alot!


Oops lastly i wanted to add the DPC LATENCY Report

USBPORT.SYS irq 1.722.228 dpc count 323.145
dxgknrl.sys irq 1.656.621 dpc count 1.019.604

CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 3511 MHz
Measured CPU speed: 1 MHz (approx.)


Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.


WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature.






_________________________________________________________________________________________________________
MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.


Highest measured interrupt to process latency (µs): 653.853243
Average measured interrupt to process latency (µs): 1.537601


Highest measured interrupt to DPC latency (µs): 118.696820
Average measured interrupt to DPC latency (µs): 0.463837




_________________________________________________________________________________________________________
REPORTED ISRs
_________________________________________________________________________________________________________
Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.


Highest ISR routine execution time (µs): 64.741669
Driver with highest ISR routine execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation


Highest reported total ISR routine time (%): 0.311886
Driver with highest ISR total time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation


Total time spent in ISRs (%) 0.386145


ISR count (execution time <250 µs): 1172351

ISR count (execution time 1000-1999 µs): 0
ISR count (execution time 2000-3999 µs): 0
ISR count (execution time >=4000 µs): 0




_________________________________________________________________________________________________________
REPORTED DPCs
_________________________________________________________________________________________________________
DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.

DPC count (execution time >=4000 µs): 0




_________________________________________________________________________________________________________
REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.


NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.


Process with highest pagefault count: chrome.exe


Total number of hard pagefaults 1068
Hard pagefault count of hardest hit process: 413
Highest hard pagefault resolution time (µs): 107566.973227
Total time spent in hard pagefaults (%): 0.035623
Number of processes hit: 15

Hello thanks for answer my thread, well actually I'm not running any antivirus because i really don't need it, i just disable my Firewall, Window Defender, Window update, etc etc its because im Using windows 8.1 pro, and i did a clean install of it, and them i manually downloaded all windows updates through Microsoft Catalogue update, so everything here was pretty much in good standing, and no i don't overclocked my pc i just activate an option in bios called (extre-profile memory) and my cpu went from 2.9ghz to 3.5 and memory mhz from 1300 to 1600, and my cpu temperature up from 50 to 56 nothing else and still performing well as always, by the way yesterday i saw a interesting post:

Url:
Windows: Line-Based vs. Message Signaled-Based Interrupts ... - Guru3D.com Forums
And i follow some instructions about chaing PCI drivers from Line-Based to Message Signaled-Based Interrupts (MSI)


And suddenly my pc start to feel more responsive, i open back the Latency Moon but now i have dpc count kinda high as usual
Anyway here is the MsInfo (had to use Mediafire)
MsInfo

and Publish- snapShop

About the xperf how many time i need to run the test because my upload speed is like 5-10kb per second and trace files are like 20mb to 100mb omg :(

"Wait until the computer has gone through a period of stuttering slowness".
If you get the problem, start the tracing and stop it: just 20-30 seconds could be ok.
Then you can ZIP the trace.
I tried few moments ago: 10-20 seconds resulted in about 14.5MB of trace, zipped to about 1.55MB (with 7zip - ultra).
