![]() 1920x1080), which does help on a lower-performance system. I infer from the VRAM usage that you are using a relatively low res monitor (e.g. The very high GPU utilization you're seeing is not being driven by any sort of memory constraints.you have 4GB of VRAM on the video card, and only 2.5GB committed. Just to be clear, Windows 7 can handle anything Windows 10 can w/r/t P3D. I'm not smart enough to advise you on what you should upgrade, only you know given your budget constraints, but I will share that my 1080Ti x2 SLI runs around 21% GPU loading with terrain texture tweaks maximized. I notice that with my 11GB VRAM that my utilization usually runs about 7.2 GB. This level of utilization is expected with a 4GB card, which is one of your several limiting factors. If you increase the resolution of terrain textures you might see a difference but that is only due to a change in GPU processing. This utilization is entirely dependent on the processes going on within the GPU and you have no direct control. Process Explorer is indicating that 2.5 GB of the total 4 GB VRAM is in use. The video card will use a small amount of system resources for cache and if it runs out of VRAM it will start using system RAM but this is not the case according to your Process Explorer. System RAM is on your motherboard (16GB), "dedicated video memory" is on the video card and might also be known as VRAM. your video card has 4GB of "dedicated video memory" and "dedicated video memory" is not system RAM. I think there is a confusion of terms here. I understand that GPU dedicated memory is system RAM that can be used for graphics. I have 16GB of system RAM, 4GB of GPU RAM, but my Process Explorer stats (see below) show only 2.5GB of GPU dedicated memory. Why do my W7 display stats (also below) show Dedicated Video Memory as 4GB? Presumably that's just the GPU RAM and not GPU dedicated memory.Īlso, what does GPU system memory do? I seem to be using a tiny fraction of the limit, - is this something that can be utilised better? I'm wondering if this is something I could increase to obtain better performance. I do have two questions though, - I understand that GPU dedicated memory is system RAM that can be used for graphics. I have 16GB of system RAM, 4GB of GPU RAM, but my Process Explorer stats (see below) show only 2.5GB of GPU dedicated memory. I read that P3D4 is somewhat limited by your processor (I have an Intel I5), so I was a bit worried that spending NZ$900 on a new graphics card might achieve very little, but I checked my computer's performance yesterday and found that my GTX 970 seems to be the bottleneck. ![]() ![]() I've recently bought some very demanding scenery (OrbX Netherlands TrueEarth) and realised that my current setup (Windows 7) can't really handle it, so I'm thinking about buying a GTX1080 to replace my GTX970.
