Well, ReyalP, it doesn’t seem it’s technically impossible afterall as I’m experiencing it. It’s just that we both don’t know what it actually is as the best way for you to see would be to be in the place and observe the things that happen.
I think we should start from the things we can be sure of… I have noticed that I have totally no network issues, with ET or with any other game either. Never had any problems with my ISP (if we don’t count repair jobs causing some sh*t and such). Lagometer shows clean graph, that’s something I really can read clearly. No red/yellow spikes when shooting, moving or standing still. Ping is also as fine as it can get on servers close to me. I actually even did some tracert tests with the different IP’s (random, google for example, my nearest ISP router etc) and saw nothing out of ordinary. So unless you got any more ideas for that, I’d say network isn’t causing this unless it’s something weird about the server or my client that does not show up in ping or lagometer. I can actually provide you with a screenshot of my lagometer in-game. The following one was captured while I was on a Finnish server (in order to get the best ping possible) : http://img167.imageshack.us/img167/3416/lagometereb2.png
Sorry if the picture is a bit dark, for some reason paint (long live paint!) made it look like that. I would have taken a direct screenshot with the /screenshotjpeg command but it appeared to bee too fuzzy to see clearly. In that one there’s every pixel visible. Well, it looks like rather clear to me (I’m not a lagometer expert, don’t get mad if there’s something “I should have seen”. But I’m wondering… In both the blue and the green lines, there’s some empty spots in them. Is that normal? If not, it could be a partial reason for this problem, eh? I made my own conclusion about the green line as my ping was low enough for the lagometer to register some spots with a graph too small to be seen in the meter. Correct me if I’m totally wrong or something.
There is no difference between shooting a wall and shooting a player, except that you also get a hitsound when shooting the player. Watching your demo, I didn’t notice any difference between the wall shots and player shots. Given that I can’t think of any conceivable way this would be different on different systems, my conclusion is that you are mistaken about the demo playback results.
I’m sorry if it doesn’t fit the technical facts or make any sense to you but it’s just how it goes. It may feel like absurd but believe me, that’s the best way I can describe it. By the words of one wise man: “If the facts don’t fit the theory, change the facts.” Err… maybe not, but maybe, just maybe, this time this is an exception. And what comes to the different computers having different results, my best guess still is the processor causing it. Here’s a quote from AMD’s official site about the Dual-core optimizer and what it should do. Maybe that will shed some light…
The AMD Dual-Core Optimizer can help improve some PC gaming video performance by compensating for those applications that bypass the Windows API for timing by directly using the RDTSC (Read Time Stamp Counter) instruction. Applications that rely on RDTSC do not benefit from the logic in the operating system to properly account for the affect of power management mechanisms on the rate at which a processor core’s Time Stamp Counter (TSC) is incremented. The AMD Dual-Core Optimizer helps to correct the resulting video performance effects or other incorrect timing effects that these applications may experience on dual-core processor systems, by periodically adjusting the core time-stamp-counters, so that they are synchronized.
And I’d like to note again, the most accurate measure of time I can see myself having the lag problem for the first time is when moving from a single-core system to a dual-core system. Here’s another ‘testimonial’ just from the same thread here, I’m quoting Reflex@Aka Sven now:
i have dual core 5800 amd since i bought this one i got the problem so hmm should the problem be the dual core ??
If it would be about the processor as I highly doubt it would be a kind of ‘external’ cause to this - not being either the game or my network…
But if you need any additional information or demonstration, I sure can hand them to you. You mentioned something about cl_avidemo but doesn’t it only give you footage with no sound? And you also mentioned cl_wavefilerecord, that’s a totally unknown thing for me. I assume it records some game audio in to a file that I could send here, right? Tell me what do you want me to record with them and I’ll do it.
