Kensington Trackball Orbit® Optical Trackball The return of the trackball as an alternative to the standard mouse After decades as a niche peripheral, trackballs are enjoying a quiet renaissance. Designers and users are rediscovering their compact footprint, ergonomic benefits, and precision — and modern technology (optical sensors, Bluetooth multipoint, configurable software) has made them far more pleasant to use than the ball-bearing devices many remember from the 1990s. When trackballs first appeared The trackball predates the modern computer mouse. Early trackball concepts appeared in military and industrial systems in the late 1940s and early 1950s; the device evolved from large, mechanical control balls used to position indicators on radar and battlefield displays. Over time the idea migrated into commercial computing and specialized control consoles, then into consumer peripherals as personal computers and graphical interfaces became common. How a trackball works (simple ...

Understanding Ray Tracing in Gaming
What is Ray Tracing?
Ray tracing is a rendering technique that simulates the physical behavior of light to create lifelike graphics. Unlike traditional rasterization, which handles light in a more generalized way, ray tracing calculates the color of pixels by tracing the path that light would take in the real world. It accounts for shadows, reflections, refractions, and more by simulating the interactions of light rays with objects in a scene.
How Does Ray Tracing Work?
Imagine a beam of light hitting an object and the complex way it scatters, reflects, or gets absorbed. Ray tracing algorithms compute these interactions to render images with realistic lighting effects. This process involves shooting rays from the viewer’s perspective into the scene and calculating how these rays interact with objects, much like how radar works.
System Requirements for Ray Tracing
Ray tracing is computationally intensive and requires robust hardware to perform in real-time. For instance, games like Cyberpunk 2077 with ray tracing enabled recommend at least an Intel Core i7-9700 or AMD Ryzen 5 5600 processor, an NVIDIA GeForce RTX 2060 or equivalent GPU, and 16 GB of RAM for 1080p resolution4. The requirements scale up for higher resolutions and more detailed ray tracing effects.
Is Ray Tracing Necessary for Gaming?
While ray tracing enhances visual fidelity, it’s not strictly necessary for an enjoyable gaming experience. Many games rely on rasterization and other techniques to produce high-quality graphics without the performance cost associated with ray tracing. Moreover, not all games support ray tracing, and its absence doesn’t inherently diminish gameplay quality.
Ray Tracing and 4K Gaming: Is It Worth It?
The debate on ray tracing’s worth in 4K gaming is ongoing. On one hand, ray tracing can significantly improve visual realism, making 4K gaming more immersive. However, the performance impact is considerable, often requiring top-tier GPUs to maintain playable frame rates at such high resolutions. Additionally, the visual improvements may be less noticeable at 4K compared to lower resolutions due to the already high level of detail provided by the ultra-high-definition resolution.
In conclusion, while ray tracing is a groundbreaking technology that pushes the boundaries of graphical realism, its necessity and value in gaming, particularly at 4K resolution, depend on individual preferences and the performance trade-offs one is willing to make - and gpu price... As for me i can experiment with it, but dont see i need to use it in my 4k gaming on big screen in stable 60hz, not to mention above 100hz.
