June 17, 20178 yr It's easy to demonstrate which GPU settings (AA, resolution, etc) can bog down GPU, AND it's also easy to demonstrate how specific slider groups will impact GPU greatly, mainly being on the Lighting slider group in V3. What I have no idea about IS WHAT ROLE DOES THE GPU PLAY in the scenery detail sliders, the cloud density sliders, and so forth. I have a GTX Titan original which according to certain benchmarks is able to benchmark somewhere around 60% of what 1080Ti FE can do, so this suggests to me I will be able to move for example terrain/cloud shadow distance & quality sliders further right than I can currently, and means GPU will likely be less of the culprit in not being able to maintain 30FPS which I need as I'm vsynced to the monitor at 30mha. What I've always wanted to know is what role the GPU plays in all of the Scenery slider group: detail, LOD, autogen, vegetation, etc. These currently to me seem to be more CPU limited, or maybe approaching 100% limited? Love to hear Rob A's analysis or SteveW's on this if you're out there. It will help me plan for my next build, after which I will likely upgrade to P3D V4. Thanks!

June 17, 20178 yr Looking forward to seeing submissions in this thread. I need to bring my CPU temps down from 80c, down to 65c-70c. I'll be happy then. Brian Nellis

If your cpu is running at 80C - you might need a better heat solution or possibly thermal compound. FWIW, I've found that a lot of people put way too much TC on and defeat the purpose.

Thanks Dan, that is useful for me though not ideal because it doesn't do so well in quantifying what the ratio is on CPU:GPU in the BOTH CPU+GPU group of sliders. This is probably nigh to impossible because of dependencies and other variables.

Hey Brian, I run a 4.2y/o SB-E 6-core 3930K at 4.42Ghz w/ HT enabled, w/ a GTX Titan. My core temps are always under 60C at peak load a using Noctua air cooler. What I did for my PC room a few PC builds back, many years ago, is install a small thru-the-wall air conditioner unit which plugs into a wall socket and so runs on 110V. The unit was made by Sharp, and has a remote control with it. It runs at 3 speeds for both air conditioning and 3 speeds for fan only. The output vents are aimed at the back of my PC case about 8" away from the case. The one 6" fan in that side of the case is in the direct path of the a/c output. During winter months I can use fan only and keep CPU temp <60C. In the hot summers I need a little a/c in the room anyway, so it works for both a room cooler and a PC cooler, and of course works for your future PC builds ultimately. It's low-pitched hum noise but doesn't bother me, and sometimes I will use stereo monitor headphones anyway and can't hear the A/C running.

I put a fresh lot of tc because when I fired the game up for the 1st time, temp was circa 90c. Putting the fresh tc on water cooler def helped and dropped it to current temps of 75c-80c. anyway, I've only had it installed for a few days. More optimising to follow. Hopefully I can get it down more. thanks Noel also. Good tip. Brian Nellis
