unfortunatly generally speaking the game, specificly the client is not built to make full use of a multi processor system, I will not bore you with the why. I'm Sure others here will offer better solutions maybe, but for now I would lock the hl process to proc 0 (1st core). Without doing that you might wind up with one of your hl threads executing in such a manner that previously expected timings are no longer panning out as expected which would unexpected behavior. The jumpyness is likely related to a frunky timing issues with threads executing on different cpu's, if you lock everything to proc 0 this probably will avoid it, you could try locking hl process to proc1 and leaving everything else on proc 0 to try for max performance though on the client end I doubt it would make much of a difference. I dont know the internal architecture of the amd dual cores, but if they share any sub components like l2 or l3 cache that might be where the issue comes up as well. I've seen some freaky issues on HT systems where different threads keep overwriting each's data in the l2 cache causing all sorts of wierdness and very poor performance, very easy to spot in the case of SQL servers.
I'm digress though.. as I'm not really helping anwser your question. If your not alone on this then I'm reasonably sure Valve is aware of this an working to resolve it or provide a workaround. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Steve Rabouin Sent: Tuesday, December 20, 2005 6:22 PM To: [email protected] Subject: [hlds] [OT] Not HLDS, but client related: AMD Dual Core Bug in HL1 Engine -- [ Picked text/plain from multipart/alternative ] Hello, I know this isn't the right place, but I'm unable to post a new 'ask a question' on the steampowered.com web site (can't find the 'ask a question' tab). Additionally, nothing can be found on the steampowered.com forums reguarding this issue. When I play HL1 TFC, I am getting 'kickback' issues, where I seem to lag for a second or two every two seconds. Well, that isn't very playable. To resolve the issue I need to set the hl.exe affinity to one of the processors only and then I can play normally. Further more, after crashing the game a few times and re-entering a game server, with both cpu affinity set on the hl1.exe, I am also sometimes getting some form of speed cheat. I can shoot 16 bullets in 1 second and recharge. I am flying through the map (but.. with the kickback issue). This is really a problem for me, and I don't wish to have this 'speed cheat'. This seems to be a common issue, I've spoken with other people who have the same issue than me on a dual core system. Any idea how to resolve this? I'd like to use the full potential of my cpu. Thank you. -- _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlds _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlds
