Whenever I play some games that heavily utilize my VRAM, when my VRAM use hits 4088MB or so (out of 4096MB), I sometimes a crash (CTD) with Windows error that reads something like "Running Low on Resources". All other resources, like system RAM (16GB), page file (4GB), free OS drive space (8GB free), game drive space (6GB free), etc. are not running out. I do not use any AV programs, do not use any Anti-Spyware programs, do not have any 3rd party services (like Adobe or Chrome or whatever else) enabled, do not have any StartUp items, and do not have any Scheduled Tasks items. All I run in the background are Steam (with video overlay disabled), MSI Afterburner (with video overlay disabled and without RivaTuner Statistics Server), and ASUS Xonar DGX Audio Control Panel. My PC is clean, orderly, updated, and optimized. I read in another forum that these errors were caused by Aero effect, which needs some VRAM to function properly. I'd rather have those few 10-20MB of VRAM dedicated to some textures and/or graphics than Aero... Is there a way to fully disable Aero in Windows 10? I already disabled Transparent TaskBar in Personalization options, which supposedly disabled Aero, but it didn't prevent the errors from happening... They happen only in heavily modded Fallout 4 and Rise of the Tomb Raider when I use "Very High" setting for "Texture Quality" on my 4B VRAM GTX 980, even though the game recommends 6GB+ VRAM cards for that settings. EDIT: I also have Start10 installed, which over-writes native Windows Personalization settings and can create TaskBar Transparency even with TaskBar Transparency turned off in Windows Personalization settings. I disabled it by setting Opacity to 100%. I am not sure if that is enough. Are there other options I need to disable in Start10 to disable the use of Aero?
