There is no single fix for every “out of memory” crash in S.T.A.L.K.E.R. 2: Heart of Chornobyl. Start by checking your PC against the game’s requirements, updating Windows and your graphics driver, verifying the game files, and lowering texture quality. The error wording alone does not show whether the cause is system RAM, graphics-card VRAM, corrupted files, heat, or another software issue.
Work through these fixes in order
GSC Game World’s PC crash and freeze troubleshooting guide, published October 2, 2026, recommends a set of checks rather than one guaranteed fix. Change one thing at a time and see whether the crash returns.

- Check your PC against the system requirements. Steam lists 16 GB of dual-channel RAM as the minimum and 32 GB of dual-channel RAM as recommended. Both tiers require an SSD and 160 GB of available storage. The listed graphics cards also differ by tier. These are published requirements, not a guarantee that a PC meeting them will never crash. See S.T.A.L.K.E.R. 2 on Steam.
- Update Windows and your graphics driver, then restart. Install available updates for both, reboot the PC, and try launching the game again.
- Verify the installed game files. In Steam, open Library, right-click S.T.A.L.K.E.R. 2, choose Properties → Installed Files → Verify integrity of game files. The official verification guide says missing or corrupted files found by the check are downloaded automatically.
- Lower texture quality first. GSC’s PC performance optimization guide explains that higher texture settings use more GPU VRAM. Lowering textures is therefore a useful first test when graphics memory may be constrained. If the crash continues, try reducing other demanding graphics settings. The crash guide also suggests temporarily disabling DLSS or FSR as a diagnostic test.
- Close overlays and unnecessary background apps. Shut down apps you do not need and temporarily disable overlays to check whether they are contributing to the problem. This is a troubleshooting test, not proof that any particular app caused the crash.
- Check CPU and GPU temperatures while playing. If temperatures are too high, improve cooling or reduce the workload. The official crash guide also suggests lowering the frame rate or enabling V-Sync when overheating is the cause.
- If the problem began after an update, test without mods. Disable mods and check for available game updates. Official announcements advise disabling mods if stability problems occur after an update; that does not establish that a particular update fixes every out-of-memory crash. See the official announcement archive.
What “out of memory” may mean
System RAM and GPU VRAM are separate resources. An error mentioning memory does not identify which one is under pressure. GSC’s performance guide specifically notes that higher texture settings demand more VRAM, which is why reducing texture quality is a sensible early test; it does not prove that VRAM is the cause of every crash.
Likewise, meeting the game’s RAM requirement does not rule out a driver, file, temperature, settings, or software problem. Use the troubleshooting sequence to narrow down the cause before buying hardware.

Should you upgrade RAM or your graphics card?
Consider a RAM upgrade if your PC is below the listed memory requirement or diagnostics indicate system-memory pressure. Before buying, check that the kit matches your motherboard’s supported DDR generation, available slots, and existing memory configuration. Steam lists 32 GB of dual-channel RAM as recommended, but that specification is not evidence that every player needs an upgrade.
Consider a GPU upgrade only after identifying a graphics-memory or performance limitation. Compare your card with the requirements and try the settings and software checks first. The available guidance does not establish a hardware purchase as a universal fix for this error.

Send persistent crashes to official support
If the crash continues after these checks, collect a DxDiag report and attach it to a support request. GSC’s DxDiag instructions say to press Win+R, enter dxdiag, select Save All Information, and save the report. Then contact GSC Game World Support and include the report along with a short description of when the crash occurs and which steps you have tried.
