GPU Usage at 80% when rendering

I recently got RTX5090 and I was wondering is it's normal that its usage stays at around 80% when rendering in Cinema 4D using Redshift.

I have selected the OC Mode from the Asus software that came with the card.

Is it bottlenecking?

totally normal, if not a bit low! you wanna be getting as much juice as possible out of that thing! you can change the maximum % in your c4d preferences. i think it’s 90 by default so probably okay to leave it where it is

Ah, thanks for the reply! I will try to experiment with a bit higher percentages, since I'm on a tight schedule to render a long animation. Let's see if that makes any difference on render times...

make sure to close any other applications which might be eating into the GPU resources! good luck!

Those 90% are allowed VRAM usage.

Hehehe thanks! It was through a government funding for freelancer artists. The 70% of the price was covered!

Redshift doesnt utilize a GPU 100% ever. Still is fast, uses less power and generates less heat.

Thanks, good to know!

GPU usage meters aren't really accurate when it comes to a lot of different applications. If you're concerned, run a benchmark as see how you stand up against similar hardware. Personally, I don't like to OC them either. These cards already run pretty hot. If the goal is to get reliable performance around the clock for the next 4+ years, is extra 5% speed boost worth it? Not while they cost a kidney to replace.

Yeah, I get what you mean.

The temperature is pretty low though, sitting at 59-60°C steadily when on OC. I'm reading that it's normal operating temperature is 70 to 80, so I thought it could stress itself a bit more without problem, no?
