I’m soon getting a new computer with high end computer parts, but don’t know if I should really spend the extra buck on a **Nvidia RTX** graphics card rather than a **GTX** graphics card. I couldn’t really find many videos about **raytracing** with an **GTX** video card in UE4. And I don’t know if having a **RTX** card really makes a difference from a **GTX** card when using UE4. Does anyone have experience on using **GTX** cards with UE4 **ray tracing** or does anyone have any info to share with me about raytracing with a **GTX** card? But my final question; **Is Nvidia GTX graphics card good enough to run UE4 raytracing?** _Keep in mind I’m not buying a RTX just for UE4 I’m just asking what difference will a RTX card have over a GTX card in UE4._ ---

Hello Jamaican Meat, If you want to go into real-time raytracing, a RTX card would definitely preferable, as they’re engineered around real-time ray tracing and it’s problems. Using a non RTX (consumer level) card will have serious performance issues with real-time ray tracing as they don’t have the necessary components (RT cores) to run well. Otherwise the general performance is better than their GTX counterpart. Just a friendly advice, don’t overdo the formatting of your questions, as this makes them unnecessarily hard to read. Hope that helps. Regards, Vecherka. ---

Thank you Vecherka your response helps me a lot. ---

I don’t think Ray tracing (DXR) in Ue4 even takes advantage of the Tensor cores in RTX cards. So in that case the only difference in performance in Ray tracing will be the base performance of the gfx card. ---

Hi Razman27, RT cores are not the same as Tensor cores. If you want to, you can take a deep dive into NVidia’s whitepaper on the NVidia Turing GPU Architecture ( [https://www.nvidia.com/content/dam/en-zz/Solutions/design-visualization/technologies/turing-architecture/NVIDIA-Turing-Architecture-Whitepaper.pdf](https://www.nvidia.com/content/dam/en-zz/Solutions/design-visualization/technologies/turing-architecture/NVIDIA-Turing-Architecture-Whitepaper.pdf) ). I’ll provide an excerpt here anyways: > RT Cores on GeForce RTX GPUs provide dedicated hardware to accelerate BVH traversal and ray / triangle intersection calculations, dramatically accelerating the ray tracing process. On GeForce GTX hardware, these calculations are performed on the programmable shader cores, a resource shared with many other graphics functions of the GPU.
