Since the tone of your post is a bit self righteous let me help you out.
The majority of the people with these issues cant do simple things like defrag a drive or clean your caches. Maybe if people learned the proper way to take care of their 1000 plus systems they can maybe get full use out of them.
And this is coming from someone running 8 gigs of Ram on an i3 yet was able to create and fully play his own mod with no issues. There are ways to maximize your PC's performance. Learn them.
Like I writed >>> " I play with mod or not, it's the same! I play many other game in single/multi who are more beautifull/powerfull than 7DTD, I nerver need to quit the game to refresh memory during +4h playing! "
About all around PC in general, I'm not a pro at 200% certaintly but I'm not a noob too, cause it's my work to repair/sell/administer PC's hardware/software & lan/server ect...
Anyway my PC with 8gb only don't have any problem! I play nearly +70% of all FPS's game since the last 3 years at least, screen size 1920x1080, no lag fps, no need reboot, no pb memory, no pb gpu/cpu, never need to quit the game to refresh the PC/memory, I can stream & record in the same time for 1h-4h without any pb, card video is setting to max quality & in game video setting too, nothing special is run in backroom ect...
So why not with 7DTD?!
So what I really wanted to say, it's time to TFP to stop be obstinate & must think to really work about the optimization of this game!
Cause it's like that since a10.3 & so since 2 years minimum where there's not really good optimization & because I do not see too much interest to add things if it is to slow down the optimization of the game even more...
& I do not say that by malice, If was me that will be what I will do for every one who can play this game with good optimization for both the game version and the server version!
& about people who buy your game, you are maybe in the top but that will no mean people are happy & mostly who continue to play it!
There's +/-3000 servers in the world of 7DTD & +50% minimum of this have 0 players online all times...
I remember when I started with a10.3 it was the opposite, +60% had +/-8 players all times...
In last december, I was playing on a french private server (very hight performance) with a god bot & good mod for a good gameplay, 24h/24h there was 40/40 players, & then 3 month later now the max players it was only +/-10 because no optimization
& I reapeat, I do not say that by malice...
& last thing, you have forgotten, most of people don't have a pc gamer very high range...
& the game is in alpha stage of development, true, but there's other many type of game who are in alpha stage too who are optimized!
For this time, I'm quiet, I just said what I think well cause I follow this game since a10.3 & so TFP need change the perception of things...
