Choose the exact game and edition. Compare minimum and recommended configurations, check SSD requirements and diagnose launch, graphics or AI-turn problems.
A minimum configuration promises neither a particular frame rate nor resolution or turn duration. VRAM capacity is not a GPU performance ranking; an older game’s 2 GB RAM requirement is not a recommendation for an entire current computer.

Edition and current installation
Complete and HD Edition are different products. HD Mod, HotA and VCMI have their own instructions; HD Edition requirements do not establish compatibility with those projects.
What to check on your computer
For large maps, consider the specific mod and engine too. VCMI requires Complete or Shadow of Death data. When comparing slow turns, use the same save, AI and versions; displaying a larger image and calculating a complex turn are separate workloads.
Launch, graphics or AI turns?
The game will not launch
Record the exact edition, build, operating system and full error message. A crash before the menu is not a frame-rate measurement. Verify a clean installation before adding a mod.
Low visual smoothness
Use the same scene, resolution and settings. Change one item at a time: shadows, effects or resolution. Record the result and retain the change that helped.
Long opponent turns
Compare the same save and AI. Map size, active player count and engine are part of the test; comparing two different maps does not isolate the computer’s contribution.
A DirectX library is missing
Microsoft distinguishes Windows DirectX from optional legacy libraries such as D3DX9 and XInput 1.3. Its June 2010 package adds these components without changing the system DirectX version. Follow the game’s installation instructions for the particular missing component.
Requirement source
Numbers come from the linked store pages. Diagnostic steps are editorial advice, not an in-house benchmark or automatic verification of your computer’s compatibility.
