Horizontal scanlines

[Raist]

Fact is I'm here for answers and not for an unemployed volunteer providing false facts.

um.... about that. This is a user to user forum, so you are going to get help from the players more so than SE employees. Read the sticky welcoming you to the forum if you don't understand that point. Should also point out that many of these "unemployed volunteers" actually have ties to the industry, either as currently employed technicians/developers/project managers or those who once worked in such capacity in the past but have now changed jobs.

As for the asking of a screenshot... it is a valid request. Yes, a screen capture from within the game may not show anything, but then again it might if it were a graphical anomaly being generated within the game engine due to bad settings or otherwise corrupted assets. Otherwise a screenshot in a more literal sense (as in, take a picture of your screen with a camera and post it) would show what may be happening in post process due to issues with your hardware. So.. yes, it is a valid request, as it would help to clarify just exactly what you are experiencing. What some people think are scanlines are actually something else. For instance, you could have highly unstable memory/GPU/shader cores due to inappropriate clock timing and/or voltage settings, or problems with cooling the components... or any number of other things that could be off within the system. Such things can cause all manner of visual artifacts... having a picture of what you are actually seeing can help those with experience with such things to provide their input based on that past experience.

Again... key words there... experienced users providing you their input based on their past experiences in an effort to help you troubleshoot your specific problem(s). That is how SE intended this forum to be used.

As for your 650 watt PSU... if that is not a problem yet, it may become one eventually. That card itself requires 2x 6 pin power connectors... that means 150 watts needs to be available from the extra connectors (75 watts per 6-pin connector), in addition to the potential 75 watts that can be drawn from the PCI-E slot. The recommendation is a minimum 500 watt PSU for an "average system", considerably more if in SLI. But... that is considering average configurations with average usage. The gaming enthusiast is going to put much more demand on their systems--things like more/faster memory, more advanced cooling, higher clock rates, which ultimately lead to higher voltages being used (ie, you need more watts to keep it stable). And that 145 watts is based on reference design... third parties can tweak clock settings and such, which may result in a higher power requirement in the long run.

Just as an example, your CPU alone could be pulling anywhere from 90-200 watts, depending on what you have and how hard it is working. That is just the CPU, not accounting for any additional cooling that may be in play, other devices on the motherboard, drives, etc. Now consider that even with a certified PSU, you may only be getting around 80-90% of it's rated load under the harsher conditions (high load, high temps, etc.). That is why you want a certified model, generics may only give 60-70% under similar conditions. It becomes even more critical if your PSU has some age on it... even high end models can suffer up to 20 or 30% degradation of their capacitors after about 3 years--the cheaper ones can be double that (not to mention losses that could be happening on your motherboard as well if it has some age on it).

Let's also not forget the line conditions of the wiring in your home... your outlet could be running anywhere from 96 to 128 volts, and is likely a 15 amp circuit. If you aren't running any line conditioning devices, depending on what all is on that circuit you could have some strange things going on that impact the efficiency of your system. I have actually seen cases where monitors had to be plugged into separate outlets because of a weird interference showing up on screen. There are some great UPS models that can help mitigate some of this... simple to install, and well worth the investment if your area has screwy power surges/brownouts and such.

So, depending on what all you have, you could in fact be walking a thinner line for THIS game because, unlike other games that are far more optimized, it is hammering all your subsystems at once and putting far more stress on your power supply by comparison. If you haven't done so yet, you may want to run your system through some power supply calculators to get a clearer picture of what you need for your configuration and playing environment, just to be on the safe side.
