About pimax gpu catalyst setup
I don’t know much about intelligent frame repair first, but the general meaning is that intelligent frame repair is to run the game with the lowest frame reduction (usually half of the maximum refresh rate) in a complex scene, and then on the basis of this frame repair, such as refresh rate of 90, in a complex scene, the lowest frame reduction is 45.Generally speaking, gpu catalysts are used together with intelligent complementary frames. Only when intelligent complementary frames are needed can gpu catalysts play a role
So how much is appropriate for gpu catalyst to be turned on?I tried a game and used FPSVR frame count software:
First, I set gpu catalyst 0. In complex scenes, the frame number dropped from 90 to 45 in an instant, and the average frame number also dropped to 55. The gpu occupancy rate was only 50%, and many graphics card resources were wasted.
Then, I set the gpu catalyst, high, such as setting up to 5, I found in complex scenes, no longer fall frames, is running 90 full frames, and the frame number is an average of 90, but the gpu occupancy rate, an average of more than 90%, and most importantly, the graphics often caton, as to why caton, may be the graphics occupancy rate is too high, and super resolution, sampling, may also be other reasons.
Therefore, I set gpu catalyst 2.5, and the number of frames dropped to 45, and the average frame number also decreased. However, the average frame number did not drop as fast as when the gpu catalyst was 0, but slowly, and finally reached the average frame number of 60!That’s 5 points more than when the gpu catalyst was zero!
Finally, I set the gpu catalyst 4.5, and the frame number of the result showed 90, and the average frame number no longer kept falling, but the value of 89 floating up and down, about 89, and the picture is no longer stuck, but I’m afraid to burn the graphics card…The graphics card is still running at a high load, 95% of them have appeared, and the temperature has soared to over 80 degrees (I plan to set the gpu catalyst to 4 next time).
When does a gpu catalyst work best?
-
If the game runs into complex scenes, the graphics card occupancy rate is low, and the frame number is also very low, then the game optimization is poor, at this time the gpu catalyst has the best effect, which is what I said above.
-
If the game runs in a complex scene, the graphics card occupancy rate is high, and the frame number is also very low. At this moment, the gpu catalyst improves the effect is also poor, because there are not many remaining graphics card resources available, the forced promotion will only cause the jam, and the frame number will not rise much
(you can also reduce the viewing Angle or pitoo picture quality, which reduces the graphics card occupancy, which also means that you can allocate more graphics card resources for the use of gpu catalyst functions, anyway, all kinds of robbing Peter to pay Paul…)
- As for running the game, when the graphics card occupies a high or low rate and the frame number is high, gpu catalyst is optional and useless
In addition, after setting up, you must restart the helmet, otherwise the setting will be invalid. I suggest that you directly click on the room Settings (not the real room Settings, but forcing the helmet to restart), then immediately turn off the room Settings and start steam vr
The game I tested, after repeated testing, the average frame number by 50 frames, directly increased by 30 frames, to 90 frames, full promotion, full refresh rate frame number to run, graphics card occupancy rate from about 50% to about 90%, and the picture is no longer stuck, also more fluid than the low frame number

关于小派gpu催化剂的设置
先谈谈智能补帧，我了解的不多，大致这个意思，智能补帧是遇到复杂场景，就降低最低帧数运行游戏（通常是最大刷新率数值的一半），然后在此基础上补帧，比如刷新率是90，遇到复杂场景，就降低最低帧数为45。一般来说gpu催化剂，是搭配智能补帧一起使用，需要智能补帧的场景，gpu催化剂才能发挥作用
那么gpu催化剂开启数值多少才合适呢？我试验了一个游戏，并用了fpsvr测帧数软件：
首先，我设置gpu催化剂0，遇到复杂场景，帧数由90瞬间降到45，平均帧数也狂降到55，而gpu占用率才50%，很多显卡资源浪费。
然后，我设置gpu催化剂数值过高，比如设置为5，我发现遇到复杂场景，不再降帧数，是满帧数90运行，且平均帧数也是90，但gpu占用率狂飙，平均达到90%多，而且最要命的是，游戏画面经常卡顿，至于为何卡顿，可能是显卡占用率太高，而分辨率超级采样不够用，也可能是其他原因。
所以，我又设置gpu催化剂2.5，结果降帧又数到45，且平均帧数也下降，但是，平均帧数下降速度没gpu催化剂为0时那么快，而是缓慢下降过程，并且最后还是能达到60的平均帧数数值！这比gpu催化剂为0时，其数值多了5点！
最后，我设置gpu催化剂4.5，结果帧数显示90，而且平均帧数不再不停下降，而是数值89上下浮动，大概保持在89左右，并且，画面不再卡顿，只是我怕把显卡烧了…显卡依然高负荷运行，95%都出现过，温度狂飙到80多度（我下次打算设置gpu催化剂为4）
什么情况下gpu催化剂发挥的效果最大？
1，倘若运行游戏，遇到复杂场景，显卡占用率较低，而帧数也很低，那么说明这个游戏优化的较差，此时gpu催化剂提升的效果最好，就是我上面说的情况。
2，倘若运行游戏时，遇到复杂场景，显卡占用率较高，而帧数也很低，此刻gpu催化剂提升的效果也差，因为没多少剩余的显卡资源可用，强行提升只会引起卡顿，帧数也升不了多少
（也可降低视角或者pitoo画质，这样降低显卡占用率，也意味着能分配更多显卡资源，用于gpu催化剂功能的使用，反正各样拆东墙补西墙…）
3，至于运行游戏时，显卡占用率较高，或者较低，而帧数都很高时，gpu催化剂可有可无，无用武之地
另外，设置好之后，必须重启头盔，否则设置失效，我建议直接点击房间设置（不是真的房间设置，而是强制头盔重启），然后立刻关闭房间设置，启动steam vr
我测试的那个游戏，经过反复测试，平均帧数由50帧，直接提升了30帧，达到90帧，提升满了，满刷新率帧数运行， 显卡占用率由50%左右，提升到了90%左右，而且画面不再卡顿，也比低帧数时更流畅
