Memory consumption with different maps (3080 upgrade)

[NoName73]

Hello,

this is kind of a follow-up to a follow-up. Given the recent price drop I upgraded to a 3080-12GB and reevaluated the memory consumption of the currently available DCS maps to get a feel for the performance increase. Maybe its helpful to anyone, link to the orginal thread down below.

Management summary
New graphics card: ASUS 3080OC-12 GB TUF; using Gaming Profile @1785 MHz
Old graphics card ASUS 1070Ti (8 GB) Cerberus; using OC Profile @1746 MHz
System is i7-11700K, 32 GB DDR4-3200, 980 Pro (OS Win10 Pro), 970 Evo (DCS 2.7.16.28157), 24" 1920*1200@60 Hz.
All FPS-Values on new card taken with Vsync enabled (*).
Anybody notice lately how beautiful DCS can look at times?!

Aditional remarks
- base memory consumption around 4 GB, clean start
- FPS capped to 60 via Nvidia control panel, very fluid experience in combination with Vsync
- Vsync now possible, with SSAA = 1.5 FPS drop significatly; still experimenting with AA und texture filtering
- usage of system memory seems to be higher when VRAM is maxed out (see Normandy map)
- test done with single A-10C (i), memory consumption with F18 oder F16 is a bit higher
- settings could be turned up without any FPS drop so far; vis. range = extreme, water = high, scenary detail = 1
- CPU usage tends to be higher with the new card
- even a (naivly created) mission with a massive MLRS M270 and M109-barrage now delivers 20 FPS with Vsync during the attack sequence; old system with i7-4771 basically frozen
- Time Spy score: 1070Ti = 7149, 3080-12GB = 16809 (OC Profile @1815 MHz); FSE: 9073 vs. 20762 (OC profile)

Settings (for both cards)
Textures     high
Terrain      high
Water        medium
Vis. range   ultra
Shadows      flat
MSAA        2x
SSAA         off
SSLR         on
SSAO        on
