benlisquare posted a topic in General DiscussionsFor those who haven't been following the recent Intel security debacle, here is a short, summarised summary: Intel screwed up with security on all CPUs it made in the past 20 years, due to a base architecture flaw. Security patch was released for affected CPUs, which fixes the security flaw. Security patch massively downgrades performance. Security patch affects all syscalls. nVidia GPUs heavily rely on syscalls because they don't have their own integrated pipeline to do this, while Radeon has it since GCN 1.1 and up. Basically all nVidia GPUs will have performance downgrade alongside with Intel CPUs if they're used together on patched systems. There will be no performance downgrade only if nVidia GPUs are paired with Ryzen CPUs. Performance downgrade is anywhere from 30% to 61%, based on benchmarks on systems with the security vulnerability patch. Yes. Really. Intel just now cancelled future gen of CPUs. Brian Krzhanich sold a lot of stock and ran away before Intel's shares started falling hard. Since World of Warships heavily relies on CPU calculations, there is almost a guaranteed framerate drop for anyone using an Intel CPU once you've installed the security vulnerability patch, and even more so for anyone using a Intel CPU + nVidia GPU combo due to the syscall issue, including myself. If you choose to not install the security vulnerability patch, you are putting yourself at risk, as the vulnerability allows level 0 access through the CPU. This means that hackers can directly write to your BIOS.
1. Description The game client uses an excessive amount of GPU resources while displaying the home port screen, to the point where the GPU overheats and reaches extremely high temperatures. In fact, the port screen uses more GPU resources than actual in-game battles; the GPU fan speed and temperatures happen to be markedly lower whilst in-battle compared to at the port screen. Currently it is winter in Australia, however during the summertime this may potentially cause housefires if players leave the game running for long time durations, idle at the home port screen. In addition, I'd presume that players with high-end nVidia cards would have a much more severe circumstance compared to mine, and this is also likely to be the case for people who have much more poorly ventilated machines compared to mine. 2. Reproduction steps Run the game, leave the game sitting idle within the home port screen for long durations of time, record GPU temperatures. 3. Result The following temperature chart shows the changes in GPU temperature whilst in-battle, for comparison purposes. Units are in degrees Celsius. The battle begins immediately after the sharp dip from 60 degrees Celsius (at the time when the game was minimised and the Windows desktop was displayed), and reaches an average temperature of 81 degrees Celsius during the battle. The following temperature chart shows the changes in GPU temperature whilst left idle in the home port screen. Units are in degrees Celsius. The time period spent within the port screen is immediately after the second dip; for comparison purposes, the period directly preceding the dip is the in-battle temperature shown earlier. Whilst at the port screen, the temperature reached a maximum value of 86 degrees Celsius before I ALT+TAB-ed to desktop to take a screenshot of the temperature reading. Had I not done so, the temperature would have continued to rise, given that the upward parabolic curve has yet to fully plateau. 4. Expected result The port screen should not overutilise GPU resources, to the point where the GPU generates more heat at the port screen compared to actual battles. Given that players are often likely to leave the game running idle whilst at the port screen (e.g. looking for food/drinks), the GPU utilisation should be at least the same as a battle, if not less. 5. Technical details While testing the temperatures as described above, the following graphics settings were used: Dxdiag: http://pastebin.com/P2qnR9S0 Addendum: My computer has removable dust filters attached to the fans, and I clean them every two months.
