I noticed the time it takes to reroll a map getting longer for each successive reroll and an increase in RAM usage after each reroll. Below are the numbers to corroborate that.
CPU: i5-9600K (overclocked to 4.8Ghz all cores)
RAM: 32GB
GPU: GTX 1080 Ti
OS: Windows 11
Initial RAM used prior to game launch: 3.9GB
RAM in use after game loaded: 5.0GB
| Reroll | Time (m:ss.ms) | RAM used (GB) |
|---|---|---|
| 1st* | 1:09.80 | 7.8 |
| 2nd | 1:37.50 | 9.0 |
| 3rd | 1:49.25 | 10.1 |
| 4th | 2:20.59 | 11.5 |
| 5th | 2:09.96 | 12.5 |
| 6th | 2:27.28 | 13.5 |
| 7th | 2:41.94 | 14.2 |
| 8th | 2:54.83 | 15.4 |
| 9th | 2.51.75 | 16.4 |
| 10th | 3:01.85 | 15.4 |
| 11th | 3:21.56 | 16.4 |
| 12th | 3:50.08 | 17.0 |
| 13th | 3:44.97 | 17.5 |
| 14th | 3:52.19 | 17.7 |
| 15th | 4:15.05 | 18.5 |
| 16th | 4:26.41 | 18.9 |
RAM in use after game exit: 3.2GB
CPU usage was only pegged at 100% for about 12 seconds near the start of the load and 12 seconds near the end, the rest of the time it was steady at 25%.
*1st reroll is the initial map load after starting the game
