Hey guys,

So I have an nVidia K5200 graphics card, which has 8 gigs of ram. However, while working in the live viewer and while rendering, I notice my Vram usage is capping at around 600 mbs. It says that I have 5 gbs free, however I'm not sure how to access them. Is there a setting a need to adjust? I'm running OctaneVR for C4d, and have a PC with Windows 10 (which I read affects RAM usage). I was planning on investing in some Titans based on what I've been reading, but wanted to make sure I was fudging something on my end before I make the investment. I feel like Octane is running very slow on my computer. Any insight would be greatly appreciated.

Hi jmfrackl ,

I am not sure you understand what VRam is. Your scene is loaded into your Vram, I guess the scene you tested with takes around 600 mb. If you have a larger scene, more vram will be used. That has nothing to do with how fast octane is running on your machine. Octane is not slow on your pc because it's not using your vram but because your card is not well fit for GPU rendering. Even a card with less Vram will be faster if it has more/faster cuda cores. If you want a more accurate or in depth explanation of vram, I suggest you read the manual.

Cheers

Welcome to Octane! Sadly, K5200 is a total puss. It only scores a paltry 65 in OctaneBench... less than that of the 6.5 year old GTX 580, which gets 67. https://render.otoy.com/octanebench/res ... ingleGPU=0 Quadro GPUs have always been woefully weak in Octane. Prolly always will. They are designed for pushing millions of polys on your screen. A 1080Ti will be roughly three times more powerful in Octane.

Except that the quadro is the fasted benched so far . Quadro GP100 : 228 vs gtx 1080 TI 197. Then again the quadro is 7k a 1080 ti 800 bucks .

D'oh! I stand corrected. I didn't know they put out a Quadro that actually gets a decent Octane score... just ass-u-me-d... but regardless, they obviously suck for Octane.
