Skymaxx Pro showing Negative VRAM for GPU

[dreamboxlouisville]

Hi All,

First I love Skymaxx Pro. I fly Xplane on a 27i iMac with the GTX775. As most programs for my airline are windows based I have partitioned my Drive to install a Windows partion. I have noticed though when I set my skymaxx settings it shows a negative amount of VRAM that it's using. When I fly on the MAC side it registers my full VRAM capability. Does anyone know if I something is set wrong or something special I have to do with this setup. I feel like it's not using my VRAM to the most of its capabilities and therefore hurting my performance. Any insight would be greatly appreciated. Thanks in advance. I've also attached a copy of my xplane log which shows the negative impact towards the bottom.

The memory usage we report comes straight from your video driver. I would guess the negative value is its way of telling us that it's actually swapping into your system memory out of necessity, which is very slow. This isn't surprising; you've got a third-party aircraft, it looks like you've cranked up Skymaxx Pro's cloud draw distance all the way, and you've got a bunch of custom scenery too - all on a video card that I believe only has 1 GB of on-board memory.

I think the easiest thing to do would be to hit the "reset" button on SkyMaxx Pro's configuration screen. Turning up the cloud draw distance can have a big impact on VRAM usage and performance, and I don't think your system is powerful enough to handle much beyond our default settings.

Thanks I will def try that. I should have included my system specs as well. I currently use an iMac 27" with the 3.5 i5 Processor with 8Gb of onboard RAM and the Nvidia GTX775 with 2Gb Dedicated memory. Here is a screenshot of my settings for Skymaxx

You might also consider turning off cloud reflections if you can live without them - that can help performance by a surprising amount.
