Can I Run Unreal Engine Without a Graphics Card?
Unreal Engine Without a Graphics Card
Despite what many people believe, Unreal Engine is not impossible to run without a graphics card. In fact, it’s possible to run it with a minimum system requirement of just eight GB of RAM. Obviously, this amount is not sufficient if you want to run multiple applications at once, and you may experience lagging if your system is not able to handle all of them at once.
If you want to run Unreal Engine without a graphics card, the CPU is the main factor. The CPU is responsible for most of the processing work that goes into developing a game. Heavy work processes include compiling code and shaders. These processes are notoriously slow, so a CPU with multiple cores can handle them without any problems. A good choice for an inexpensive, midrange or high-end processor is the NVIDIA GeForce RTX 3070, which features great single-core performance and is compatible with multiple monitors.
Upscaling is another common solution. Upscaling is a method in which applications render most of the frame at a reduced resolution, then enlarge it to the desired output resolution. Upscaling allows for a significant performance gain, but may result in a less detailed final image. Various upscaling algorithms have been developed to minimize loss of quality. The stock UE4 version has two separate upscaling algorithms.

The main difference between the two is the language of scripting. In Unreal, scripting is done in C++. This is an easy-to-learn language, and the game engine itself uses visual scripting. It is node-based and can run on a lower-end PC setup. By contrast, Unreal requires a high-end graphics card. Therefore, the system requirement is also a factor.

CPU speed is also an important factor. CPU speed is not as useful without a GPU, as it can’t run visual effects as fast as a GPU. But, the other requirements are the same. A GPU is crucial for 3D content creation. A GPU is responsible for the lighting and visual effects, while a CPU is more useful for compiling. It also runs 3D render engines, which are the main pieces of hardware required for Unreal Engine.
If you’re unsure if your computer is powerful enough to run Unreal Engine, you can consider using a dedicated server for data processing. These servers are often stripped of graphics, making them more effective for data processing than video games. However, a dedicated server is not 100 percent useful for data processing. Because Unreal uses non-deterministic rendering, different results may occur if you run the simulation on different machines with different frames rates.
UE4 uses real-time ray tracing. An example of this is a Star Wars short video called “Reflections.” This video was created with textured area lights, ray-traced shadows, and cinematic depth of field. Moreover, the video was created on a workstation powered by four Volta architecture GPUs. However, if you can’t afford to upgrade your graphics card, you can still play Unreal without a graphics card.
