 Hello there and welcome back to GameDevacademy. I'm Shane thanks for joining me again and in this video What we're going to cover is GPU rendering in Blender which can make your rendering go like so many times faster So if we just head straight over to my PC, I will show you how to do that what we've got going on so as you can see we've got the BMW render file that you can get from the Blender website, which is a really good like benchmark for how long renders take And what we'll do first of all is just render on the CPU so you can see here so You might be on one of these kind of Tabs if you're in your own project if you go click on this little digital camera looking thing here This is for rendering and we've got cycles is the render engine we're using and we're currently set to CPU Which is very default So what I'm going to do is just set this rendering so we can see how long this scene takes on the CPU And then we will switch to the GPU. So let's go render and render image. Oh And we're done. Are we? It looks like we're done. So I've got my cup of tea. Oh, it's a nice cup of tea as well Okay, so we can see That this scene has taken me Three minutes and twenty three seconds to render who has that kind of time to spare I could have died in that time. We need to go much faster So let's get GPU rendering on the case and we'll go much much quicker. So we'll close that for a minute, right over here Then so if I now try to change the device in the render settings from CPU to GPU compute It's actually grayed out, which means it's not going to work So even though it's telling me GPU know if I start rendering, it's just not going to work So here's what we need to do put it back to CPU for a sec We're going to go to edit and preferences Make sure you're on the system tab here and then we need to go to CUDA and we're going to enable the GPU So in my case that is the Nvidia GeForce RTX 2070 super. It's the best I could afford at the time I built my PC Okay, and we just need to make sure that it's also turned on for optics because why not? If you choose to and if it makes sense You can also tick your CPU and you can render on both but in a lot of cases if you're rendering on your GPU I would recommend leaving your CPU free So I'm just going to turn that off Okay, so that's what we need to do here I can close that and now when we switch this from CPU to GPU It's not grayed out. Yes There is one more thing we need to change that So just scroll down here to performance and just make sure that you expand that section We are going to leave threads to auto detect but tiling GPU is just like bigger tiles. So we're going to change that from 64 to 256 Like so now we have enabled GPU rendering. So shall we render again and see how much faster it goes? Yes, we shall so render and render image. Let's try again And what I'm not going to do is make a cup of tea because I won't have time Because it's going to go so much faster And we're just finishing up so you can see that that one took 20 seconds That is a heck of a lot faster than we had previously So there are some other settings and tweets you can do if you want to get your rendering faster overall But this is how to enable and make use of hardware rendering in the form of gpu So that brings us to the end of another video. Thanks so much for watching If you want more videos like this then let me know in the comments. What would you like to see me create next? You could also support me and the channel over on patreon in the same way that the wonderful people whose names will be on screen have done And I think that's it. I think I can end the video here. So I'll see you in the next one. Bye
