I am just getting back into 3d art. Been out for a while - started painting with... paint when my mouse shoulder started getting unbearable. But now I want to do something with all those models and software I spent so much $$ and time in collecting. Anyway - I'm running Carrara (which I love) 7Pro and I'm finding the vertex room slowwwww. If I am pushing or pulling around a shape, it won't refresh very fast (and I swear it used to be faster on my computer). If I sweep off the stage- over to the tool bar, it will refresh, but if I don't it doesn't refresh any changes... for several seconds. Even with a simple cube. Any ideas?

I sometime have this problem but with models with thousands of polygons, not a simple cube. Sometime, I wait until the édited or deleted polygons move or disappear but that work as soon as I click in an empty zone. I think it's a shortage of memory on the graphic card if I use the openGL, but I'm not shure. For a simple cube, it's very strange...

Hallo omniusplay.

Can you tell us your hardware parameters (CPU, RAM, GPU, GPU-RAM) Maybe you had set your Interactive Render Settings to "Software". It maybe faster when you set it to OpenGL. You can find it here:

Thank you! I switched to Software and now it refreshes instantly with a simple cube. My settings were just like your settings for OpenGL and nothing was changing. Maybe my OpenGL is broken? Can it be broken? I'm kinda joking because I don't know why it is not working with OpenGL...

Ok. OpenGL is the graphics hardware accelerator... My iMac: 2.66 GHz Intel Core i5 4 GB 1067 MHz DDR3 memory Version 10.7.5 (afraid to upgrade with all my old software) Carrara 7Pro

Graphics: ATI Radeon HD 4850 : VRAM 512 MB -

Seems like I've increased VRAM in the past... can it still be done on newer iMacs?

Ok, I'm answering my own questions here. I can't increase the vRam. Should be enough for Carrara anyway. Maybe something else is going on. I could save my Runtime out and do a fresh install of Carrara 7Pro.

Um... seems to be fine now. I switched it to Software, and it worked better. Went back in and it was on OpenGL and it refreshes in the vertex room like a champ so I don't know what happened. Anyway - I'm not messing with it now. Thanks for the help.

Could be that the OpenGL drivers got tangled up during an update to the OS since you installed C. It might have reconnected correctly once you switched into and out of it. In all cases, very glad it's working.

Thanks Kixum. I wasn't looking at it right. Open GL still isn't working in the vertex room, but I dragged in a high-vertex object and even in software mode in the vertex room, it refreshes good enough to use.

Ok, I want for the upgrade to 8.5pro, but I can't seem to get a runtime from C7Pro into 8.5. It installs, but no images, seems like it reads the content, but no images at all show up. Any ideas?

Just for fun, check to make sure your OpenGL drivers are the most up to date. Try to get drivers from the manufacturer of the chipset, not from anything sent with your machine. Drivers direct from the chipset manufacturers website are usually a much better bet.

I'm suffering from the massive Frontier internet outage right now. I'm actually surfing off a hotspot from my cell phone.
