Re: Deathworld goal?

Defender capsules are extremely powerful. With just red/blue/military science, you can get 15 follower count and 13 damage. That's good enough to take out large bases with big (blue) biters. On death world, I would make military science and damage upgrades the top priority (before blue science). Gun...

Re: Defensive turret line order, what turret is best up front?

Does anybody test, what happens, if you have only flamethrowers, which are placed out-of-range of spitters behind a wall? Do spitters attack the wall then? They sometimes stay out of turret range and attack the wall. If the wall is in repair range, the bots get continuously killed. If it's outside ...

Re: Defensive turret line order, what turret is best up front?

I put the flame turrets in the front for a simple reason - they have loads of hit points. If large groups of enemies arrives including behemoth spitters, a few of them might get a shot before being roasted and gunned down. Gun turrets go down after a few hits, while flame turrets will be able soak ...

Re: CPU performance benchmarks

It looks like the Linux version doesn't support your maps. Both Factorio 1.0 and 0.17.79 fail with the same error I mentioned. Running the Windows version of Factorio under Wine could load your old map (123_311219.zip), but huge pages don't get used. I ran a benchmark for 10'000 ticks: Performed 100...

Re: Anyone Ryzen Benchmarks?

Could you please check my "little sandbox" on your system. True, you have only 32 GB of memory, this is too little Factorio doesn't like your save (I tried with 1.0). (I was able to extract the zip, so I don't think the download is corrupted.) 82.739 Warning Map.cpp:340: Map loading failed: Couldn'...

Re: Anyone Ryzen Benchmarks?

An interesting result. Is it possible another test, at the same frequency and with the same memory, but without these kernel tweaks ?? To see the difference, before and after :) there is a very big difference between 114 and 85 (the usual result is also with good memory :) The result is 94 without ...

Re: Anyone Ryzen Benchmarks?

When using huge pages on Linux, Ryzen 3900x is as fast as a i9-9900K. I'm getting 114UPS: https://factoriobox.1au.us/result/880e56d3-05e4-4261-9151-854e666983c9 Transparent huge page support needs to be enabled in the kernel: /sys/kernel/mm/transparent_hugepage/enabled:always [madvise] never /sys/ke...

Re: [0.18] Sea Block Pack 0.4.5

Upgraded my seablock save from 0.4.4 to 0.4.5 (and factorio to 0.18.18) can no longer craft 'iron-stick' wanted by most buildings. As far as I understand Angels smelting is replacing iron stick with iron rods, but it isn't playing nice with Seablock: I started a new game with 0.4.5. 'iron-stick' ex...

Re: Parrallel processing in games & applications

You are mostly testing the memory bandwidth here. Not latency. It is possible to hide latency by using more thread and utilizing multithreading or very smart software prefetching, but that would complicate the code base a lot, and still doesn't work fully with all entities easily. I'm not saying it...

Multithreaded performance

Having done quite a bit of multi-threaded programming, the claims that Factorio is memory-bound didn't make sense to me. The memory controller of current CPUs has quite a bit of parallelism and doesn't easily saturate with a small number of threads. I ran some benchmarks with parallel Factorio insta...
