My DCS takes a very long time to start up

[beastfang]

My DCS takes a very long time to start. I saw that it only takes about 30 seconds for others to start DCS, but it takes me about 5 minutes.
And others use laptops, but I use a desktop.
I reinstalled the win11 system and the DCS game. My CPU is i9900K, GPU is 4090, memory is 32G, and the C drive and game drive are high-speed M.2

Can someone help me please

You mean to start the game to get into the main menu, or starting a mission?

Your preload radius is maxed out at 150000 which is really really high, especially with 32Gb of RAM. This will be loading a large amount of the map and textures unnecessarily. Drop this down to 60000 or lower, could do 30000. This will effect loading time when starting a mission.

If you haven't already then also add an exclusion in your anti-virus software, e.g. Windows Defender, for the entire DCS installation folder and restart your PC.

For comparison purposes do your friends have the same number of modules and maps as you? I see the F4 sounds might take a while, do they also have the F4?

Unrelated side note, you have the game arguments `--force_enable_VR --force_OpenXR` which are not needed (force_OpenXR is redundant now as well).

A:this seems look like a good idea.thanks,i will try

A:I don't know where to adjust the relevant parameters. I noticed that you also have the VR device Quest2, and mine is Quest3.

Thank you very much,bro

@beastfang This is where it spends time... 2.5 minutes. Try to exclude the folders in Defender like suggested.
Cheers!

I just got a new system and was really disappointed at how slow it was loading DCS.  Then I remembered to exclude it and WOW does it make a huge difference.

"Drop this down to 60000 or lower"

How do you drop down the preload radius? Where do you go? Just wondering. Mine loads fine, but would like to know about doing this to improve loading speed.

preload radius is in DCS options within game or changing it in the launcher.

Thank you, I appreciate it.

Jester speech... thousands of small files windows didn't very designed to operate with (it spends longer time in checking user access rights than in file reading), but after they are cached in standby RAM, next loading must be much faster

Correct. Usual recommendation (most definitely from me) to reduce it down, especially if you're seeing memory issues and long load times. 150,000 (some unit I don't know as miles sounds a lot) of area is loaded into RAM. Sure, this loads faster next time, however it may be an area you never travel to, or not for awhile, so is redundant. SSD's these days are pretty damn quick so don't need to precache that all up front. This also has the side effect that when you run out of VRAM on your graphics card it starts paging to RAM, and when RAM gets low, it starts paging to disk...which is way slower. So essentially having more RAM available for headroom is good.

150000 is also unfortunately (I reckon a really bad bug) set as the default when you select the default VR graphics option in DCS settings. That setting is sometimes used by people with low spec'd machines, which actually consumes way more RAM
