[ Converted text/html to text/plain ] Does this mean, that multi-core AMD cpu-s will have a performance(?) handicap while running the new dualcore-source-engine? (Or more simple: Are we better with a multi-core Intel CPU in the future?) Locutus Alfred Reynolds írta:
We simply note the fact that the rdtsc return value went backwards between two consecutive calls. RDTSC returns a monitonically increasing value per CPU so it going backwards means that we jumped to a different CPU and the counters aren't being kept in sync (certain dual core AMD architectures suffer from this feature). When we detect that jump backwards we just let time slip a little (as there is no reliable way to know exactly how much time was lost), we only use this timer for non-critical timing functions (i.e not in running the game simulation). - Alfred Gary Stanley wrote: How are you calculating the drift for each cpu? (code snipplets would be nice) I've always wanted to know how to 'detect' TSC drifting. :) At 01:47 PM 1/4/2007, Alfred Reynolds wrote: You can ignore that assert, it means that you have a dual core CPU and the RDTSC counters on each core do not stay in sync (a "feature" of certain AMD cpus). We have code to handle this issue, the assert is just in place so we could determine what hardware setups have the problem :) The next server release should remove that assert (as we have answered the question now). - Alfred Saint K. wrote: Hi,, Im getting the following error on my clean CS 1.6 install: reliabletimer.h (73) : Assertion Failed: m_nPerformanceCounterEnd = m_nPerformanceCounterStart i've searched google for this error, but apperantly it only occures at windows machines.
