Games on the computer are a great way to “kill time”, have fun and just relax. Even without being an avid gamer, a person often has his own preferences in the field of game development. Some people love shooters, others can't live without strategies.
Back in 2006, a real event was the release of STALKER: Shadow of Chernobyl. The game has gained millions of fans around the world. Latest version, Call of Pripyat, was released in 2009, after which the number of fans of the game increased sharply: the atmosphere of the Chernobyl nuclear power plant is so captivating that even adults can sit for hours at it.
Unfortunately, many users are complaining that the XRay Engine bug is preventing them from enjoying the game at all. What causes its appearance and how to get rid of it? This is exactly what our article is dedicated to.
What is XRay?
In order to find out how to solve the problem, you need to understand its root cause in more detail. Let's start with the fact that XRay is a game engine that is used in all parts of Stalker.
It was created specifically for this game, and this happened back in 2001. Since the STALKER project itself turned out to be simply an epic “long-term construction”, it saw the light of day only five years later. At first, the developers intended to use it exclusively with DirectX 8, but by the time the first part of the trilogy was released, they added support for DirectX 9. In 2008, when the release of the long-suffering Clear Sky was announced, version 10 was also added there.
Finally, “Call of Pripyat” also received DirectX 11. However, given some “roughness” in the game code itself, the engine was unable to fully unleash the full potential of the 11th version.
What is the manifestation of the error?
This moment cannot be confused with anything. The game suddenly stops and then crashes to the desktop. Since the dialog box describing the error code depicts a large beetle, the XRay Engine is often called a “green disaster” and a “misfortune beetle” on fan forums.
However, enough lyricism. What is the reason for the appearance of the “beetle”?
Reasons for appearance
Alas, but there is no clear answer to such burning question simply not. The developers from GSC did not particularly comment on the reasons even at the time when the company still existed, and now it is completely pointless to hope for detailed answers.
Using the trial and error method, it was found that the game most often crashes on the computers of those users who do not have the latest drivers installed for their video card. So if you don't know which version of this software is installed on your machine, it's time to update it.
We update the game itself
If you witnessed the appearance of Clear Sky, then you remember very well all those “flattering” epithets that players awarded the developers. And there was a reason for it! It was, in fact, completely impossible to play, and the XRay Engine error was still minor!
Just look at the immortal snipers and the completely empty “Dark Valley”! I was able to play normally only with add-on 1.5.04, and all the saves that were made on previous versions, didn't work. In short, if you have the Internet, don’t be lazy and go to the developer’s website. All existing patches for all games in the series are there, so you just need to download and install them. In this case, the XRay Engine error in Stalker will probably appear much less frequently.
Pirate versions
Since the developers did not take into account the interests of end users, the game is protected from illegal copying by the well-known StarForce system. It is not surprising that many users prefer to download NoDVD even in cases where they have licensed disk with the game.
Unfortunately, many of these “pills” cause the XRay Engine error to appear. What to do if you don’t want to spoil the StarForce operating system, but you also don’t want to see the “green bug” all the time?
Alas, there is only one way out. Buy the game on Steam. Since in this digital content store the game is also available to foreign users (where StarForce is prohibited in principle), you will definitely get rid of the problem.
Other reasons
Another important factor that may contribute to the error may be your computer hardware. Too new or old components may well not get along with the mysterious Ukrainian engine, after which you will constantly be haunted by the XRay Engine error. "Call of Pripyat" on this moment is the most recent version of the game, which has the least common hardware problems. "Shadow of Chernobyl" and " Clear sky"in this regard, they are much older, and therefore they often completely refuse to be friends with new video cards.
Mods
When “Stalker” was just released, the players’ delight knew no bounds. The game really gave a feeling of almost limitless freedom. The GG could go anywhere, being practically unlimited in the direction of his movement. As time passed, the enthusiasm became less and less.
It became clear that the developers were not going to return the cut locations, and there wasn’t enough action in the game. It was then that MODs (game modifications) appeared, sometimes making truly global changes to Stalker.
The most famous was the AMK project, without which gamers with experience now do not recommend completing “Shadow of Chernobyl”. Some mods were very successful, some not so much. But almost all of them have an XRay Engine error. “Call of Pripyat” is much less susceptible to this phenomenon for the reason that there are much fewer mods for this game.
So if you are using a MOD, then there is only one way out - to communicate with its developer directly or to sift through hundreds of pages of forums, where players sometimes post good homemade “patches” that, under certain conditions, can actually eliminate this error. Of course, you can’t always hope for this, since in the case of the XRay Engine (“Call of Pripyat” in particular), it’s difficult to say anything concrete.
Cheats
Other players, who find some levels too difficult, often get too carried away with cheats, with the help of which they can build for themselves an unlimited number of weapons and equipment, and get the best artifacts at their disposal.
As usual, you have to pay for everything. In this particular case, this is expressed in a loss of program stability, when the XRay Engine error in Stalker begins to appear every few seconds. If this happens, simply try looking for a different version of the cheat. Fortunately, today they can be found in thousands of copies on the Internet. Finally, try to pass the difficult level honestly! Perhaps this way you will get much more pleasure from the game.
"Shamanism"
Alas, even the most logical and correct, at first glance, methods fail when it comes to this game engine. For example, if you are not playing with a “native” resolution, this may well be the reason for this error.
Your monitor resolution is 1280x1024, but do you prefer to play at 800x600? It is likely that the XRay Engine appears in Stalker precisely because of this. Change the resolution to the native one (recommended for this monitor). In some cases, such a simple measure helps to completely eliminate the error.
Sometimes the problem occurs when your page file is set to too small. Ideally, its size should be twice the volume random access memory.
How to increase the size of the swap file?
It's actually quite easy to do. To do this, right-click on “My Computer”, then in context menu select the “Properties” item. In the dialog box that opens, select the “Advanced system settings” option. Click on the “Options” button in the “Performance” item, and then select the “Advanced” tab. Then you need to click “Change” in the “Virtual memory” item, then enter the value you require there and left-click on “OK”.
Occasionally, the game can be launched if the system has less than 512 MB of memory, but you shouldn’t do this: the XRay Engine error and terrible “brakes” will still not let you play.
Finally, we need to talk about the features of the game itself. It is advisable to disable unnecessary image enhancement options. This statement is especially true when it comes to “Stalker Call of Pripyat”. XRay Engine appeared very often in version 1.6.0 when the player tried to set maximum settings quality.
And more about drivers. It is not so rare that an error plagues those users whose computers have a discrete audio card. Try updating the drivers for it, and in particularly difficult cases, disable the device from the Control Panel. Attention! Do this carefully, as otherwise you may lose all sound on your computer.
What can we say at the end of our entire story? We wish you that no errors prevent you from setting new game records! We hope that our recommendations will help you in this matter.

The engine.exe virus is a Trojan. Secretly activates a Bitcoin miner on the victim's computer - an application that solves complex mathematical problems in order to obtain cryptocurrency. And then the results are sent via an Internet channel to attackers or to a third-party special resource, but again, with the details of their “owners.” In other words, it exploits the resources of the infected PC (RAM, computing capabilities of the video card) and “extracts” money, earning money at someone else’s expense. The user, or rather his machine, inevitably becomes a miner.
Infection and symptoms
Quite often, engine.exe penetrates Windows during the installation of hacked games. Unscrupulous releasers, or distributors, " free product", those who want to further enrich themselves are strongly recommended to disable the antivirus so that the installation is successful. Those who obey this advice personally allow the malware to pass through.
Four signs of the presence of engine.exe in the OS:
- Without running any applications, the RAM and processor load is observed at 80-99%.
- Actively used network connection(Internet traffic) without explicit connections of installed trusted programs.
- Regular Windows features and applications launch and work very slowly - the PC “slows down”.
- A process called engine.exe *32 appears in the OS task manager (sometimes in several copies).
Removal procedure
1. Click "Start".
2. In the search field, type taskmgr.
3. In the task manager, open the “Processes” tab.
4. Find the virus process named engine in the list.
Attention! The malware may have a different name. When analyzing, pay additional attention to digital signature objects (column “Description”). And also on the level of resource consumption (CPU column). Inflated readings (more than 70%) are a clear sign that the process is related to the virus.
5. Click on the image name (object) being examined right click.
6. In the context menu, click the “Properties” section.
7. On the “General” tab (properties window), in the “Location” column, copy into notepad or remember the path to the virus application folder.
8. Reboot Windows into safe mode.
9. Open the engine directory copied from its properties.
Note. In most cases, it is located at: drive C → Users → [username] → AppData → Roaming → [malware folder]. The folder name varies: known modifications are x11, x13.
10. Go to the Roaming directory (click at the top of the window, in the path bar, by its name).
11. Delete the cppredistx86.exe file and the folder with the virus.
12. Close the window and press “Win+R”.
13. In the Run panel, type regedit and click OK.
14. In the Registry Editor, open: HKEY_CURRENT_USER → Software → Microsoft → Windows → CurrentVersion → Run.
15. In the Run branch (the list of keys in the adjacent block), delete the entry with the Microsoft Visual C++ 2010 parameter. This is a module disguised as a system package that autoloads the engine when the PC starts. Use the standard function: right-click → “Delete”.
16. Reboot the OS in normal operating mode.
Prevention
After the cleaning procedure, be sure to scan all media with the main antivirus, having previously updated its database, or with additional healing utilities - Dr.Web CureIt!, MBAM ( Malwarebytes Anti-Malware), Kaspersky Virus Removal Tool.
