How to determine what is causing the FPS drop? / How to do graphics system analysis?

Question

GPGPU

The thing is, Windows 10 x64 is now installed, the system is working, so a lot of different software has been installed on it, and the OS itself is a little cluttered. The problem is that when playing videos or games, the FPS is very low. At 1080p YouTube videos FPS is about 15-20 fps. In games (DirectX) FPS is acceptable, but in some places it drops significantly to 20-30 frames per second.
To identify the problem, I installed the second OS, the same Windows 10, as a result - everything works fine, the video plays without problems, the FPS is acceptable for my equipment (so a game in which there were 30 FPS on a clean OS gives out 60 + FPS).
Help to analyze the graphics system to identify what is causing this problem. The OS is working, so I spend a lot of time in it, and it takes a long time to reboot to play, rearranging the OS is not an option now. At one time, Adobe Premiere CS6 was installed on the working OS, then the FPS was even lower. The complete removal of Adobe Premiere partially solved the problem, but it was not possible to identify the source of the problem (when I noticed the problem, there were no restore points, nor even an idea of ​​what caused this problem).
Naturally, I updated the drivers (I tried both previous and stable and beta versions), virus scanning, defragmentation, etc. already done, the problem did not disappear. It can also be said with certainty that the problem is software (everything works well on a clean OS). Just in case, I will give the characteristics of the PC: CPU AMD Phenom x4 9550, GPU Nvidia 9500 GT, RAM 3 Gb.

Answer 1

RAM 3 Gb. I suspect that this is the problem. A bunch of programs hang in memory (many software packages like to run resident programs, so that they supposedly load faster later) and Windows is permanently swapped.
So turn on the performance counters (I have no idea where they are hidden in the top ten) and keep an eye on disk and memory usage.

Answer 2

Yuzayu the same top ten on a mediocre laptop. Also at one time I felt a "subsidence" of performance, and not only in games. A couple of times I put the top ten outright - it is quickly installed from the flash drive .. But after all, reinstallation is not only the demolition of the system - it is its reconfiguration and additional software. Voschem, not an option (backups and rollbacks through acronis do not count). I decided to carry out a comprehensive optimization - at the same time earn a couple of points in the insider program. Let's go to the points.
I began to hear his work, although in a parallel seven on another section, everything is fine. Therefore, data streams are heavier than a rod. Strained - hardin's my dear to me. Turned off file indexing on each partition individually- this function is important only for those who often look for files on the disk using Windows search. I don’t need it - where and what to look for in system folders, I already know, for convenience I set up grouping by type, and on the disk where I store everything, I have the perfect order - daddies Images, Installs (with subfolders Games, software etc.), Games and others contain relevant content in a structured way. If there is a need to save even non-standard - there is a folder Distributor. She's alone, it's easy to look for, if anything.
Hard's torment didn't end there. It's TEMP time. There are four of them. Two system and two user. So, we press Win + Pause (Break), select the additional system parameters on the left - Environment Variables. Here, I must say, it was not so much about speed, but about crap - a dozen dirty ones. By default, it does not delete anything after itself. So Variables. We need Temp and Tmp. I created a Temp folder on the data disk, in it - four subfolders - WinTemp, WinTmp, UserTemp and UserTmp (Although it was possible to simply number it, but it's clearer) and reconfigured the corresponding variables on them. Therefore, unloaded a little system disk. Then reboot, then - Properties of the system disk - Disk Cleanup. We wait a long time, then in the list that appears, we lay down on everything and press - clean up system files. We wait even longer. A list appears - select everything there. The list differs from the previous one in the presence of backup files of previous versions of dozens and installation files, which eat up the main disk space. Then we press OK. The garbage will be thrown out for a couple of minutes.
Next is defragmentation . Let's skip the details here. It is better if all disks are defragmented.
And the last - Antivirus. As the practice of my personal use of the built-in soft antivirus shows, it is stupid. It has its own indexing of files, therefore - extra brakes. After a week of using this mega-product, I started opening folders for a minute (or more - if it is the Download folder, where there are a lot of applications and archives). This bastard scanned them all with prejudice, and PPC for how long. There are a minimum of settings in this software - the soft ones themselves know how you need it .. The verdict is in consumption. At 10, it will not be possible to completely demolish it, therefore we turn off the Windows Defender. It is desirable, having put before it another, proven one. I have Avast. After reboot, the increase in the speed of opening folders increases significantly.
Everything with hard.
Go to Control Panel, Administration,services .
We disable or set to launch MANUALLY everything that is clearly not related to the operation of the system. I must say, do not go there if you do not know what services are.
Press Win-R, write MSCONFIG, ok, Startup section. We remove the birds from what you do not use immediately after turning on the machine. You can run the necessary program from the shortcut, but the extra software in autorun eats memory and processor resources.
By the way, here I recommend installing Anvir Task Manager and setting the replacement for the standard task manager in the settings. There is advanced autoload and, more importantly, AUTOLOAD CONTROL . That is, everything that is added to autoload will be immediately detected and a request will come out - leave it, disable it, or even shut it down along with the file ..
Farther. Desktop . This is a folder in the wilds of disk C. And it is absolutely not necessary to litter it with folders with videos, music, photos of your beloved and pictures of cute kittens from VKontakte. There should be labels. Exclusive labels! Everything else - on disk D! If there are many shortcuts, sort them into folders and leave several such folders on the table. All paths of shortcuts on the table are automatically rescanned with enviable regularity. And, although it is produced by fast - nafik do you need it?
I do not recommend cleaning the registry in the top ten - the regcliners have not grown up to it yet and can screw up.
With the correct execution of all points, you can get a real increase in productivity. And this, by the way, is not only in the top ten.
I'm waiting for comments.
